I am getting into dyeing yarn and Fiber. I find that it is much easier to dye yarn... as felting is less of a worry. I also notice that how and when I add the acid to my process changes things dramatically.
Both of these used about 8 ounces of fiber, citric acid, and Dharma acid dyes, and water of course.
This was simple kettle dyeing... the citric acid was added after the fiber was in the pot. It used less citric acid.
Here I soaked the fiber in a water and citric acid mixture... then I added it to a pot with water and brought it up to heat and the dye adhered very quickly. The two dyes hardly mingled in the pot at all.
