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.
To make them, simply soak a doily in wallpaper paste and wrap it around a balloon. Let the balloon hang overnight to allow the doily to dry completely. When the doily is dry, pop the balloon and you'll be left with a lovely candleholder!
