My friend, Mary at Fancy Fibers, organized and ran a wonderful retreat in February, 2009, at a local camp. It was loosely organized for all types of Fiber Folk to come and do their thing and just hang out for the weekend.
She planned only a few classes for the retreat. One of those was a fiber dyeing class that I ended up teaching as a last minute fill in when the original teacher had to cancel. The roving was merino superwash supplied by my friend Joanne of Terrific Fibers
The class had about 14 people in it including several first time dyers. I was very concerned about keeping the dye where it should be and off of where it should not be, and I am happy to say we were succesful with that effort.
We covered everything well with plastic and newspapers, then laid out our soaked rovings on plastic wrap. We painted these with dye stock, then sprayed them with vinegar and wrapped them tightly. We rolled them up jelly roll fashioned. We labeled them with some plastic tape and markers and put them in roasters to steam.
Each of the rovings turned out beautiful, and the fiber spins like butter.
