Fiber & Friends #3

I've wanted to dye with indigo for a very long time, probably about as long as I've been fooling around with fiber. Indigo ikat,  sashiko, shibori and batik have always been favorites in shades of blue. I even own an indigo dye kit that I have never felt competent to use.

So I was absolutely elated to find that I could take a class in Cordova from a true natural dye expert, Kathy Hatori of Botanical Colors.  I had read enough about indigo to know that it was an art, not just a 1 2 3 set of instructions.

The class was held outdoors, at a cabin by Eyak Lake. It's a great idea to dye outdoors, for obvious color-drippy reasons.

Here's our class space--a propane burner and vat for each student, with various dyed and undyed skeins hanging about. The magenta and golden skeins were for overdying with indigo. I was so preoccupied with turning white yarn blue, I never got around to the overdyes.

My main aim was to dye my 6 skeins of Cormo wool from a Juniper Moon CSA share bought last year. My plan was to just plainly dye two skeins, dye two skeins shibori-style with resist areas, and do an ombre job on the last two.

First up was the process of making the vat: stirring up the indigo powder with a little henna and calcium hydroxide.  We started in quart jars and eventually progressed to the big pots of warm water. Because making indigo dye is an organic process, there's some waiting time, but eventually you get your vat ready to go, and it looks like this:

Bubbly scum on top, and a metallic sheen. The top of the vat is blue because the dye has oxidized in contact with the air, but the liquid below the surface is a green tea color. As you proceed with your dyeing, you must constantly check the color of the dye solution, and rebalance it with additions of fructose when it veers from that tea green.

One thing you quickly learn about indigo is that your fiber exits the vat not blue, but green. Then with exposure to air, the dye oxidizes and turns blue. Intensity and depth of color is not so much the strength of the dye solution, but the number of times the item has been in and out of the vat, each dip with a pause to air and oxidize.

Here is the pair of cormo skeins tied with rubber bands and ready to go in:

 

And here is a pair of the plain skeins after a couple of trips to the vat: 

They look a bit uneven because they have picked up some of the powder from the bottom of the vat. A plain water rinse evened them out and neutralized the pH from the dye solution.

 Here are my products of the day, posed with some fishnets for added ambiance--The darker blues are the plain skeins, the lighter ones the shibori and the other two. Plus the colorful non-overdyes.  Time and the waning strength of my dye vat made my later skeins much lighter than the first two, and the ombre version a goal for the next time.

 

Yarn is famously not the only thing that turns blue on indigo day. Indigo dyers are known for their blue hands. Though I wore gloves during the actual dyeing, I got a little blue in the paws just from handling the yarn to reskein it  before its final rinse.

Yet More Yarn Yarns

Trawling (appropriate for fisherman sweater, no?) through denim yarn patterns, I think I've found what my ecru Rowan pile wants to be:

The Cornish Knit Frock by Jane Gottelier from the book Indigo Knits. I had a flirtation with the Whitby Sweater from the same book, but decided that in ecru it would look like any old aran, as it would not have the lightening effect that makes the cables stand out when using a colored yarn. Besides, Whitby is in Yorkshire, not Cornwall.

An added attraction is that the Cornish sweater was made by one of the Knitting Goddesses, Kay Gardiner of Mason-Dixon fame, and was done with the same yarn substitution I am using, Rowan Denim for elann.com Den-M-Nit. Happily for me, Kay demonstrated that the shrinkage of the two yarns is the same.

Plus there is the connection to Cornwall. My DH is from there, and we have visited family there many times.

Fisher ganseys are also on my mind because I am happily anticipating my sojourn to Cordova, Alaska this summer for the Fisher Folk knitfest:

I have always loved gansey sweaters, the look of them and their lore. I have knitted a few, and will enjoy knitting more. They are a garment that looks great on everyone, men and women, big people and little people.

And when I'm in Cordova, one of the workshops I'll be attending is an indigo dyeing session. I'm going to take my now-foofed 6 Juniper Moon CSA cormo skeins and dunk them in the pot.

For a while, I was conflicted about whether I should just do them plain indigo, or go for spaced shades of blue, or tie them up to get white spaces in the blue. Wait. Three techniques into six skeins divides evenly--I could do 2 of each! Hope the teacher agrees...
