Did you ever think of using kool-aid as a dye? me neither. But it totally works. Here are some awesome examples:
Kool-aid dye chart for fabric. It's cheaper than rit!
Koo-aid dyed yarn
Kool-aid to UN-stain (that's probably not a word) your dishes.
It has to be this specific kind, though
Kool-aid to dye hair!
I really, really, really want to try this, but I am probably not brave enough.
