I found them at Michaels, they were hanging on the wall right next to the little bottles of acrylic paint, Apple Barrel, Folk Art, etc.... Other stores that sell this type of paint may carry them too :D
Another place to check in Michaels is where they carry Donna Dewberry supplies :wink:
Here is what they look like :D:D:D
