This BFL top was dyed with jacquard acid dyes. After applying red, orange, and purple, I thought it looked horrible and squeezed out the dye within a few minutes. I was thinking that I'd redye or over-dye it at first, but after seeing the shade that it turned out, I went ahead and processed it with heat.
I spun it into a 2-ply yarn. Now I'm working on (another!) baby hat. Good thing I know a lot of babies, because I can't stop knitting baby hats.
