Then I sized the images in Photoshop and printed them out on this printing fabric that I've had forever.
It's probably not even around anymore, but there are many tutorials on Pinterest regarding printing on fabric using freezer paper and fabric.
Then I cut the fabric carefully around each image, leaving about 1/4" border and stitched the images to the center of my fabric squares. I wrapped each canvas using hot glue. Starting from the center of each side and working out from there. Getting the corners flat takes a little time. Finally, I added ribbon around the edges using hot glue.
I also found some artwork at TJMaxx. Both of the pieces were a steal, on clearance for $7 a piece.
