Looks like you just need to utilize your space a little better...have you thought of using comic book board? It doesn't cost as much as the vinyl / plastic fabric boards....usually $8.00 - $10.00 / per pack of 100....depending on where you get it....THEN, you could stand your fabric up...like the fabric shops do....you'd be surprised at the extra space you get, and....you don't have to worry about your stack falling over. Have fun
