if you have bookcases in your space, try stapling the hook side of velcro on the front edge of the bookshelf then stitching the loop side of the velcro in matching places on the back/vinyl side of flannel backed vinyl or table cloth. Hang up when you need the design wall and take it down when you don't need it. Because the back is vinyl, you can roll it up to keep the design intact (mostly) to access your shelves, to carry the "wall" to retreat, etc. You can use either a tablecloth or buy yardage at Walmart or Joann's.
