I was super excited to come across the idea of dying playsilks with kool-aid and made a couple last week for a friend's daughter's first birthday. The tie dye came out beautifully and I just assumed that the colour would stick because so many people seem to be using kool-aid to dye playsilks.
When I tested the colourfastness, however, much of the colour came out of the silks :(
Am I doing something wrong? I used vinegar, which I assumed acted as a mordant since I saw it in various posts and I used boiling water (do not have a microwave).
Anyone have experience with this and any advice? I was looking forward to making more for more gifts but don't want the colour to run out of them all!
