This is a great, Olympic-themed project to work on with a group. Cut rings out of thin cardboard, paint them the appropriate colors, and then have fun finding items to glue to each ring. Collage items can include tissue paper, pieces of chenille stems, sequins, paper scraps, and much more. You could even dig thorough your kitchen cupboards. You can hang up the rings and even continue to add to them as you find more colored objects.
