I went to Joann's, my favorite craft store, and bought 6x6 cork tiles. I then took some old frames we had and removed the glass. Then I cut the cork tiles to size, glued them in, and hung them up. Here is the finished product for their art. I am happy with the way they turned out, and the best part is it only cost me the amount for the cork..not bad for a days work !
3 boards for school projects.
