Ihave been using foam core boards for my fabrics for two years, plus I cut smaller boards for all my fat quarters also. Almost all of my fabrics are on foam core, with the exception of scraps, LOL. Just think this is the easiest way for me to see all my stash at a glance. Organized by color and holiday, i.e. Christmas, Holloween, etc. Takes alot of time to get the boards cut and fabrics folded, sorted and shelved, but so worth it. Oh, got all my foam boards at the Dollar Store. Now if I could just get the rest of the room organized!!!
