Create your own dip dyed shoes. You don't have to particularly use yellow dip-dye. I've tried this myself, and I dip-dyed my shoes blue and green instead. It really works! Make sure you have white shoes only, or else it won't work.
Bowls made of confetti! Great recycling art project--save all those leftover paper scraps (put in small bowls at each table). Collect a bunch and have the kids cut them up; Then make bowls made from confetti.
