Using a rare 50% off coupon I bought a 'Fons and Porter' Design Wall that is similiar to a Vinyl Tablecloth. It is marked with 2 inch squares and lines marking the center. I can hang it or put it away when not in use. It has grommits to hang by so it's easily removed when not in use. It was about $12.00 with the coupon and worth every cent. Wish I had gotten it sooner.
