When I was little, a fun activity I enjoyed doing was tie-dying shirts. Let the shirts sit in the dye overnight, then rinse them in cold water, dry them, and then voila- tie-dye shirts! I had my doubts about the avocado dye and only used it on one shirt, along with the onion dye. I was right to doubt the avocado dye. Also, the ice worked well to do the watercolor, though it was a bit tough to see using only one color dye.
