I made these rainbow clouds using an extra large cloud punch and craft foam. The colorful bowls are a favorite thrift score. We use them for all sorts of classroom fun; color sorting, dramatic play, and paint vessels to name a few. A diy note and tip for you...craft foam does not play well with a paper punch. When punching, use a sheet of paper (I think I used a magazine page) under the foam. This will trick the punch into thinking it is punching plain old paper and not the too-pliable craft foam. I also glued a handful of cloud shapes to blank blocks. These were used at the play dough table and were a hit! Enjoy!
