Here is the my version part, a cloth pocket on the back! Perfect for those little pieces of felt.
Here is what you need
First you lay the canvas on top of the felt, and fold it around the canvas and trim off excess felt. Then glue the felt to the wood using Tacky Glue. Felt absorbs some glue oddly, making it stiff so don’t glue the felt directly to the canvas. For extra support staple the felt at the corners. Starting at one corner, hot glue the ric rack to the edge. Pull a little if needed to get the ends to match up together.
