Post-Vinegar Soak

Posted by Daisy Aschehoug on

After unpacking from Ireland, I wanted to treat my indigo dyed fabric to make them as colorfast as possible. Turns out, the internet has a dizzying amount of advice that ranges from "do nothing" to "use a salt water bath" or "soak in vinegar." 


I chose the vinegar route. Several websites advised adding a cup of vinegar before the rinse cycle and stopping the machine so that it will soak. This strategy seemed an unlikely win with my brand and model of washing machine. I decided an old-school bucket and a few gallons of water would be more reliable. I added the vinegar let the bucket sit for two hours. 

I put the indigo fabrics into a wash with two color catchers. I haven't found that product here in Norway, but I brought two boxes with me from the US when we moved. The pieces of paper absorb dyes in the wash, and I brought them because they are fantastic when washing quilts for the first time.

As expected, the color catchers grabbed a bit of blue. And the fabrics, thankfully, didn't seem to lose much of their color. Based on what I've read, I expected some of the indigo particles to come off, and I was excited that most of the dye has adhered well to the fibers.

I hung it all to dry inside as there's no shade outside. I think the avoid-UV-when-drying rule is when the fabric first comes out of the indigo vat, but it was easy enough just to dry these inside anyway. 

Next step is to sew the smaller squares into a set of napkins. Not sure yet about the larger pieces, but I'm pretty sure they'll end up in a quilt.

It's hard to believe that just month ago I was in Ireland. Since then of course, it's been all-home-all-the-time, except the few trips to the grocery store and a few delightful walks in the woods. Strange times...

Indigo + Shibori Workshop with Kathryn Davey

Posted by Daisy Aschehoug on

Kathryn Davey's Indigo + Shibori workshop was a Saturday of pure fun. I learned plenty and happily took home lots of samples, but the best part was the simple act of getting to dip fabric into dye and watch the color oxidsize into a deep, beautiful indigo. I've been reading about natural dyes for a while, but nothing beats getting your hands dirty.

There seemed to be a lot of necessary tools, but there was also an "anything goes" feeling about the tools. Nothing was hard to find: porcelain tiles, pieces of wood, clamps, rubberbands, 5 gallon buckets. 

Kathryn added materials to the indigo dye vat and discussed various traits of indigo. She detailed several options for oxygen reducers that help the normally-water-insoluable indigo dissolve and then eventually permeate the material you want to dye.

Kathryn regularly dyes outdoors, but the wind was howling on Saturday. I was glad she spread a tarp out to create a space for us to work.

Our first task was to accordian fold fabric to clamp between two tiles. The dye only reached the edges of the fold, creating a grid-like pattern across the fabric.

We also rolled fabric onto rope and compressed it like those hair scrunchies from the 80's that seem to be coming back into style.

The indigo vat and the first glance at fabric that comes out of the vat both have a greenish tint, almost turquoise or aqua-marine blue.

There was a subtle magic in watching the color shift from that greenish tint to a true indigo.

I know indigo doesn't require mordants during the dye process, but I'll treat my class samples in a mix of vinegar and water to set the dye. I'm not sure it's necessary, but there's no harm in taking the extra measure to prevent fading.

After that, I'll hem the edges of these little squares and see how these fare as everyday napkins in our household.

Most importantly, I found some confidence in this workshop. I started some lichen dyes last summer that are waiting for me to get my own dye space set up, and Kathryn "pulled back the curtain" to reveal how a simple set up can yield amazing results.
