At Dollar Tree they sell a 30X22" sheet of rigid styrofoam board for $1.00. It is in the paper and crafting section. I think kids use it for display boards when the do school projects and science fairs. I had purchased a package of those plastic fabric organizers and liked the concept but couldn't afford enough of them to use for all of the fabric I had. I thought about the possibility of using the styrofoam board. It is acid free. I cut the board into 11X6" pieces so there were 10 per sheet. I wrapped the fabric around those and secured with plastic paper clips. Very little money invested and I haven't had any of them break. They are inexpensive enough that I toss them out when they no longer suit my purpose but they will probably be here longer than I will. Ann in TN
