Good evening! OK, I'm totally addicted to these mini canvases. They are so much fun to make and they are a great way to get rid of extra pieces, scrap ribbon, and excess stash. The sizes are 2X2, 3X3, and 4X4. Just think of the possibilities. I bought my blank canvases at Archivers, Hobby Lobby, and Dick Blick Art Supplies. You can trade them like an ATC, give them as gifts, hang them on a wall, or display them in a cute bowl. Thanks for looking!
