Last summer, I painted a canvas bag with my pawprints! It was really fun! There was a fundraiser/birthday party/carnival, and one of the booths was making the bags. The volunteers sponged yellow non-toxic fabric paint on one of my paws, and pressed it down onto the bag. I helped by flexing my paw as it touched the bag! I made a few impressions, then they washed off the paint with a rag. We repeated it with a light green for a few pawprints, then washed that off too.
Mommy has the bag, but it's too big for the scanner, so we'll just put the link to the picture the carnival organizers took. You can see it here!
