i purchased 1" foam board (white) from home depot...about $4 a sheet-8'x4'...i bought 3 of them...then i bought wide white flannel, covered one side of each 8'x4' foam board butted them together side by side and adhered them to the wall. so i have a 12'x8' design wall... i can have a whole quilt in the works plus room of other blocks, and if anyone else is around sewing there is room for them to use too. and the blocks just stick to the flannel...like flannel story boards from elementary school. some people purchase flannel backed vinyl tableclothes and use the flannel side, some have been really 'crafty' and made a shade over a window work as one...so you can pull it down when needed, roll it up when not needed. you will use as much space as you give yourself...so if possible i would try to dedicate a whole wall, if that is not do=able any size is handy. :thumbup:
