i appreciate the challenge of finding activities where the process is the priority but there is also a take home product. printing is perfect! last week we painted on bubble wrap taped to a table with hands and foam brushes and then made prints of the painted bubble wrap. 
the product was more stunning than i expected!
we felt eric carle-esque which was a perfect lead in to c week’s exploration of the very hungry caterpillar.

We love painting with bubble wrap! Shared your post here http://siayla.blogspot.ca/2014/02/got-paint-try-painting-with-out-typical.html
I LOVE THIS! I invented bubble painting in the mid 90’s, but used the bubble wrap as a stamp. This affords a new result! I’m 68 and an artist, and et very inspired by preschool and elementary art projects! THANK YOU!
Such a fun idea with beautiful results! I’ll be sharing soon on The Crafty Crow :)
