I have bought the ones at Wal-Mart now I will have to try the ones at the Dollar Tree and the other dollar stores.
thanks for the info I am in the process of doing the same with my fabric and getting my sewing area up and running. Last year my husband passed away and now I have the whole basement to set up all my sewing crafts etc. The room he had down there, I am making into a guest room but I will still be able to store some of my fabric on the 4 book shelves he had. I am more than a little excited. It is a big basement that is completely finished complete with carpeting. Thanks again for the update on the foam core boards.
