I went over to Lovely Jan's to do a bit of dyeing today:
We used icing dyes for these. The way this type of dyeing works is that you get a mahoosive jar, fill it 75% or so full with vinegary water, add your dye, dunk in your yarn, and wait. Then just periodically add your other colours on top. If you agitate the liquid about a bit, the dye will sink down and get caught in the middle of the yarn or down the sides of it, producing really random and rather tasty results. I also dyed another skein in a kind of burnt orange in addition to this red and blue but obviously didn't get myself together enough to take a photo!
