I stapled a red checkered, flannel backed tablecloth that I got on clearance for 50 cents to the wall of my sewing room. It works great and an added bonus is that the red shows through and serves as sort of a grid. If you don't want to staple your walls, you could staple a tablecloth to your frame. I find that if you are careful removing the staples, the tiny holes are not noticeable. I used a regular desktop stapler and it holds fine.
