I've had a question from Randi on the blog about how I set up my wrap for grad dyeing, so I thought I'd add this picture. This shows that I have hung the wrap on hangers, which are then hung on a folded-up airer. The hangers are separated with clothes pegs, to keep the wrap slightly parted. As I have a very narrow kitchen, the airer can fit across the kitchen, with one end on each work surface. I would recommend simply looking at what you have available in your house, and improvise a set-up which would work for you! I hope this helps!
This second picture also shows the set-up, and was taken just after I removed the wrap from the dye, with an empty pan below it to catch the drips.
