I still don’t have any sugar free kool aid, so the sprinkling has not been tested.  Darn life getting in the way!  Unfortunately the blue wool wound up getting some rust since the pan completely dried out and began to rust a bit. That’s what I get for buying cheap pans, but it is a good lesson for the classes I’m teaching.  Take your wool out to let it drip dry.  So I had to throw out the blue wool (I might have been able to scour it but didn’t really want to mess with it).  Before I did that though, I did try and rinse out the Kool-Aid, and it did not move an inch.   The dye seems to have stuck to the wool despite the lack of heat.  This makes sense since there are individuals that Ice Dye with Kool-Aid and then do not seem to add heat.  I’m very pleased, and I will have to try this again when I have a free weekend and can do all of the steps in a day or two instead of a few days later.

Result: You can dye with kool-aid and no heat.  It does remain in the wool, however you want to take it out of your pan to dry, and rinse within a day or two.
