Indigo Shibori Scarf Tutorial

IMG_20170625_132321 (4)

Hello dear readers! I figured that it was about time that I do some straight up indigo shibori dyeing for you! I will walk you through setting up your indigo dye vat and doing a very simple shibori technique on a beautiful piece of fabric – with spectacular results (if I do say so myself). 🙂

But first, let’s chat a bit about indigo. Ah, indigo…sublime indigo. It’s such an amazing color! If you have ever toyed with the idea of dyeing with indigo, I say DO IT! Dharma Trading sells a kit for $8.49 that includes everything you need for one 5 gallon vat that will dye up to 15 yards of fabric. Ridiculous.

But I digress, back to indigo for a minute. Indigo is an ancient dye that has been in use for thousands of years. In fact, in September of 2016 Smithsonian.com reported:

Archaeologists recently uncovered several scraps of indigo-dyed fabric at the Huaca Prieta ceremonial mound in northern Peru. Believed to be about 6,200 years old, this find pushes back the date for the earliest known use of the dye by roughly 1,600 years, Cynthia Graber reports for Scientific American.

You can find a nice summary of the history and use of indigo on Design Sponge. Here are a few excerpts:

Indigo is a colorfast, plant-based dye that can come from a number of different plants, but it was primarily found in Indigofera, a tropical plant that was cultivated and became a staple agricultural crop. There are three steps to the traditional process of extracting the dye from the plant. First the leaves are fermented in a steeping vat. Then a liquid is extracted and oxidized, and from that, a blue solid forms in the bottom of the vat that is collected and dried. In the 19th century most indigo was made in British-run factories in India.

Indigo is different from all other natural dyes (apart from shellfish purple) in that it needs no mordant (a substance used to set dyes on fabrics); it is insoluble and is deposited on the fibers as microscopic particles without needing to form a chemical bond with them. The chemical properties of indigo dye remained baffling well into the 19th century. It was so mysterious and challenging to work with that, in many cultures, folklore arose around the dyeing process. In Bhutan, pregnant women were not allowed near the vat in case the unborn baby stole the blues, and women in Morocco believed the only way to deal with a particularly challenging vat was to start telling outrageous lies. All this trouble was worth the final result. Once dyed, indigo is so colorfast that it can last for centuries or even millennia.

I love the bit about outrageous lies and I love that the amazing history of indigo gives a context for dyeing with and wearing this glorious color.

Please note that the indigo I am using is what’s known as “pre-reduced indigo.” This means that the dye molecules have already been processed so that they are able to dissolve in water without the effort (and chemicals/yeast/or stale urine – seriously) that would otherwise be required. Indigo purists would probably take offense to the pre-reduced version, but this form has the distinct advantage of being incredibly fast and user friendly by comparison.

I had previously been under the impression that the pre-reduced indigo crystals were naturally derived. However, from what I understand they are what is known as a “synthetic organic.” This an organic compound that is synthesized in a lab and that is chemically identical to it’s natural counterpart.

Materials:

  • 5 gallon bucket (I got mine at Home Depot)
  • 4 gallons of water
  • reuseable gloves
  • Pre-reduced indigo crystals
  • Thiox or Color Remover
  • Soda Ash Fixer
  • Stir stick
  • Fabric – indigo works on cellulose or plant based fibers like cotton or linen and protein fibers like silk and wool. I’m using a silk and wool blend scarf/shawl from Dharma Trading.
  • Mild detergent – I use Synthrapol
  • Acrylic circle
  • Rubber bands
  • Various containers (see below)

Tutorial

Please be sure to work outside or in a well ventilated area. Also, please be mindful that indigo is a DYE and it will stain whatever you are working on or around, so take appropriate precautions. Wear gloves and don’t use any bowls or measuring cups from your kitchen! All tools should be dedicated to dyeing – so if this is not already the case, run to the dollar store and pick up a few bowls, cups, measuring spoons and containers.

1. Fill you five gallon bucket with four gallons of water. The water should be cool to the touch (between 60 and 70 degrees Fahrenheit or 15-21 degrees Celsius).

img_20170108_104108

As you can see, my bucket has been used many times for indigo dyeing. By adding chemicals and or indigo you can actually keep a vat going for many months. My last indigo vat went for about a year! Here are directions for tending an indigo vat (scroll down to the bottom of the page).

If you are using the kit mentioned above, you don’t have to weigh or measure anything! Since I generally purchase my dye and chemicals in larger quantities, I will need to weigh it all out. If you don’t have a scale you can convert grams to tablespoons or cups online.

2. Weigh your Thiox (Color Remover) and add it to your bucket. The recipe I’m using calls for 160 grams.

3. Weigh your pre-reduced indigo crystals and add them to your bucket. The recipe I’m using calls for 50 grams. I wanted a really strong vat, so I’m using 100 grams. I have read that your fabric will be more colorfast if you use a “regular” (i.e. 50 gram) vat and dip your fabric multiple times to darken the color (rather than using a strong vat and fewer dips). So far, this hasn’t born out to be true for me. However, I have predominantly dyed scarves that are washed very infrequently. So perhaps this more critical for garments that need to stand up to repeated washing?

4. Weigh out 240 grams of soda ash. Next, add a little hot water to your soda ash to help it dissolve (mine looks blue in the pic below because there was some indigo residue left in my jar). Your soda ash won’t dissolve completely but not to worry, your vat will be fine!

5. Time to stir the pot…or in this case, the vat (sorry, I couldn’t help myself!). Use a dowel or a large stir stick (I used a paint stir stick from Home Depot) to stir your dye. Stir it in a circle in one direction about 10 or 15 times and then slow down and go the other direction the same number of times. Before removing your stick, drag it along the outer edge of your bucket. This will bring the foam to the top. The foam is referred to as the “flower.” Underneath your flower, your mixture should be yellow-green in color.

6. Let your vat sit for a bit before using it. I prefer to let mine sit overnight but according to several sources you can use it 15-30 minutes after your done adding everything. You will want to be certain that the dye is yellow-green in color under the flower. If it’s not, wait another 15-30 minutes and check again.

7. Time to prepare your fabric! I’m using a gorgeous silk and wool blend (63% silk and 37% wool) scarf/shawl from Dharma Trading. This fabric is super soft and warm but incredibly lightweight. It’s truly a beautiful fiber and it takes indigo dye extremely well. It’s very important that you always wash your fabric before dyeing it. Even fabric that is PFD (prepared for dye) may have “schmutz” on it that can affect your final result. I use Synthrapol to wash my fabric but any mild detergent will work. Simply give it a quick wash and wring it out before moving on to the next step.

8. Now it’s time for some shibori! My fabric is 36 x 80 inches so it required quite a bit of folding. First, I folded it in half width wise. Next, I accordion folded it lengthwise. Finally, I accordion folded it until I had a neat little folded stack of fabric. This actually sounds much more complicated than it is. I Promise. The most challenging aspect in this case was the shear size of the fabric and the fact that the fabric was wet. But, wet fabric is KEY. You never want to put dry fabric into an indigo vat (or any dye bath for that matter) and you don’t want to wet the fabric after it’s folded because the folds interfere with the fabric’s ability to absorb water evenly.

If you have never done this before, you may want to practice with a piece of paper first. You can even dip your paper into your vat to get an idea of the pattern you will create with your folds! Here’s a diagram that should help you get the idea.

Here’s my little my stack of folded fabric…

9. Now it’s time to add a resist. I’m using two 4 3/4 inch acrylic discs that I got here. Apparently, these are intended for cake decorating, but they work great for this purpose and they are affordable. I had actually intended to use a 3 inch circle for this project, but I inadvertently ordered the bigger size, so I decided to go for it! I simply placed a disc on either side of my pile and I used rubber bands to secure it in both directions.

img_20170108_124114

10. When you are ready to dye, you will first need to remove the “flower” from your vat. I scooped mine out with a plastic dollar store strainer and I put it in a plastic dollar store container (you must save your flower because you will put it right back onto your vat when you are done). Now grab another container so that you will have someplace to set your fabric bundle when it comes out of the dye. Did I mention the dollar store? 🙂

img_20170108_124320

11. Grab hold of your fabric bundle with a gloved hand and give it a dunk in your vat. I held mine under for about a minute before pulling it out.

img_20170108_124440

img_20170108_124505

Okay, so the green leaves that look like they’re growing in and floating on my dye are actually just a reflection of the leaves that are growing up the fence behind my vat! So crazy!!!

12. Pull your bundle out and place it in a container of some sort. Let it sit for 20 minutes to oxidize. This is actually one of the coolest parts of this process. Your fabric will look green when it comes out of the dye bath and as it hits the air and begins to oxidize it will turn blue!

img_20170108_124720-1

Unfortunately, my bundle has already oxidized a bit in this pic but you can still see some green on the right side. If you look carefully at the bottom you can also see the clouds above and the leaves on the fence behind my container reflected in the acrylic disc. 🙂 🙂 🙂

13. You will need to continue to dip your bundle until your reach the color you desire (bearing in mind that the fabric will look several shades darker when wet). Depending upon the strength of your vat, this could take four or more times. Since my vat is very strong, I only dipped my fabric two times. Be sure to allow your fabric to oxidize for 20 minutes between each dip.

14. When you have reached your desired shade of indigo and your bundle has finished oxidizing, it’s time to rinse. I like to keep my bundle intact and rinse it until the water has a very small amount of blue left in it before I open it up. I do this in order to prevent the indigo from dyeing the fabric that I want to keep white. After you have opened up your fabric, rinse it until your water runs clear. Giving your fabric another quick wash with detergent will also help to remove any excess dye. This can take a little while so try to be patient (says the incredibly inpatient woman).

By the way…opening up a shibori bundle is one of the greatest joys of this process. It really is like opening a present! You never know exactly what you’ll get, which is part of the beauty and mystery of dyeing.

15. Hang your fabric to dry and iron if necessary.

16. Put the lovely “flower” that you removed from your vat right back on top. This will help to seal your vat and keep oxygen out. This is important because too much oxygen will negatively affect your indigo vat. Next, stir your vat in the same back and forth circular manner described above and put the lid on.

Here’s my result! You might have thought that I would get a circle shaped pattern…but as you can see, it turned out to be more like a square or grid pattern. I’m sure this was due to the fact that the circle was so large in relation to the size of my folded fabric stack and because I secured my stack with rubber bands (rather than a c-clamp – which would hold the resist much more strongly and result in a more well defined pattern).

IMG_20170625_125221

If you are looking for a more distinct circle or square…here’s the secret. Once you have folded your fabric place your resist (acrylic/wood circle or square – or whatever) onto your fabric and clamp it tightly with a c-clamp. In the first example below, I added some rubber bands after I clamped on my shape. The next two scarves also employ clamp resist shibori (itajime) techniques and the last piece was dip dyed into my vat. A few of these babies are still available in my etsy shop.

If you have an questions or if you have dyed with pre-reduced indigo and you have something to add, please feel free to comment!

Last, but not least, as I mentioned previously, a properly tended indigo vat can last a very long time so this is by no means the end of your indigo journey! Even if you just buy the little kit I talked about, you have lots of dyeing to do before your vat is exhausted. Also, setting up your vat really is the hardest part. Once that’s done it’s simply a matter of prepping your fabric, dipping and waiting and rinsing which is WAY easier and less time intensive than many other types of dyeing. So have at it!

 

 

 

“Mud Cloth” Pillow with Inktense

IMG_20160529_131409 (1)

Hey there! So I picked up some Jaquard No Flow when I was at a “real deal” art supply store the other day and I was curious to see how it would perform. According to the label you’re supposed to paint it onto the entire surface of your fabric and then voila you can paint with dye and it won’t run! Hmmmmm, I was a little skeptical but I was willing to give it a try. My plan was to paint on a mud cloth inspired design using naturally derived indigo.

IMG_20160526_130306 (1)

I decided to grab a white cotton canvas Ikea pillow case that I had laying around. Before painting the fabric with the No Flow, I put a piece of clear vinyl into the pillow case to prevent any bleed through.

The No Flow is really thick and it’s very difficult to see on white fabric. So I was super careful to make certain that I covered every square inch of my pillow case. I then put it outside to dry while I tended to my indigo vat.

I’m excited to (finally) be sharing a bit of info about indigo dyeing with y’all! I will definitely be doing more indigo tutorials in the near future. It’s one of my favorite dyes for a multitude of reasons. First, the color. I LOVE this color. It’s ancient and timeless and chic and classy and…sublime. Next, as a dye it’s super fun to work with. I use Pre-Reduced Indigo Crystals from Dharma Trading. This is naturally derived indigo that has been “reduced” to make it much faster and easier to work with than traditional indigo which is not water soluble and requires a series of time consuming steps to get into a workable form. My current indigo vat has been going for well over one year now. I simply add Thiox or Color Remover and/or indigo as needed to maintain it. I also love that the fabric comes out of the vat green in color and then turns blue as it oxidizes. It’s still fun for me to watch this process! Finally, I love that indigo works on protein fibers and plant based fibers and no mordant is required!

The only “con” that I can think of is that indigo can fade over time (like a pair of jeans), but that really doesn’t bother me all that much. 🙂

Although it may be difficult to see here, my vat is looking a bit grey blue and murky which tells me that it needs an addition of Thiox and indigo. Click here for instructions on how to tend to an indigo vat.

IMG_20160526_141908
Hello there! Can you see me and my phone in the indigo?

I’m adding 10-11 grams of indigo and Thiox.

Next, I gave my vat a good stir (first clockwise then counterclockwise). The bubbles that form on top are known as the “flower.”  This is a cap or crust that helps to keep oxygen out of your dye bath. You will need to remove it before you dye and then replace it when you are done.

IMG_20160526_143507 (1)

Since I’m not vat dyeing in this instance, I simply scooped up some of my dye and put it into a glass jar so that I could paint my pillowcase with it.

I decided to sketch out a design with a pencil before I began painting. As I mentioned, I was inspired by the designs in traditional African mud cloth.

IMG_20160526_145953

Here goes! Fingers crossed!

IMG_20160526_150515

Well, it mostly worked but there are definitely a few areas where the dye seems to be bleeding a bit. Perhaps a second coat of the No Flow would have done the trick?

IMG_20160526_152303

I don’t like how fuzzy my edges are! I was really hoping for crisp, clean edges! So, I decided to break out these:

This is my first time using the Fabric Fun Dye Sticks and my third or forth go with the Inktense Sticks. The Fabric Fun sticks are waxy and the intensity of color doesn’t match the Inktense. After some experimentation, the Inktense sticks took the win by a mile and I stopped using the Fabric Fun altogether.

IMG_20160526_154243IMG_20160526_155421IMG_20160526_164200

As you can see, I decided to change up my design as I moved along. The pencil lines will wash out, so no worries! The Inktense sticks are easy to draw with and when you go over them with water, they dissolve and become more intensely colored. According to the directions, they need to sit for 24 hours and then be heat set before the color is washable.

At this point, I noticed that in spite of my best efforts some of the indigo had bled through onto the back of my pillowcase. So I decided to go with the flow and brush indigo onto the entire backside.

IMG_20160526_170247

I set my pillowcase to dry and this is what I found the next day.

IMG_20160527_134339

Yikes! What’s up with that ugly yellow ring around my pillow? I’m thinking it’s from the indigo and I’m hoping that it washes out?! Regardless, I went ahead and heat set it for 1-3 minutes with my iron on the hottest setting.

Next, I washed my pillowcase in Synthrapol (which is a professional textile detergent – however, any mild detergent would be fine) and it took about four quick washes to get my water to run clear. When I pulled the pillowcase out of the water, the nasty yellow ring had disappeared! Yay!

IMG_20160527_135059

For some odd reason I didn’t take pictures at this  point. Argh! But suffice it to say that the wash water took away a good bit of my color even though I heat set everything?! Maybe this had to do with the No Flow? To remedy the situation, I went over all of my lines, first with Inktense and then with a water laden brush. I then gave the back another brush with some Indigo and I added a few black and blue lines with the Inktense for some interest.

IMG_20160527_144426IMG_20160527_141147

The pillow case is wet in both of the pictures above. so the colors are most certainly darker than they will ultimately be, but I’m liking what I see. 🙂

After 24 hours I ironed my fabric on high heat for about 5 minutes.

IMG_20160528_141859

Here it is before it was washed.

IMG_20160528_142232

My fingers are crossed that the color holds fast this time. I’m really starting to think that the No Flow interfered with the Inktense because my lines are much more clear and saturated this time.

IMG_20160529_131409 (1)

Okay, so I lost a little color in the wash, but not bad. I can’t decide if I like the black that bled out around the edges of the lines. On the one hand it gives it a bit of dimension…on the other it looks a bit smudgy. 😦  As for the No Flow it was a “no go” on this one! Perhaps it was my fabric choice or the indigo? My experience tells me that it may work best on silk with silk paints so I’m willing to give it another try at some point. In the end, this was more about the Inktense sticks than the No Flow or even the indigo.

Please feel free to share your thoughts or your experiences with any of these products! 🙂
