I am in the process of getting all my fabrics put onto boards and reorganized on my shelves. I went to the Dollar Tree or Dollar store (what ever it is called!) and I got coated paperclips. I put one at the top and at the bottom of the fabric. I bought foam board for $1 a sheet at the dollar store too and cut it up into 5 1/2" X 12" pieces. I think I got 9 or 10 boards out of each piece of foam board. I have $30 invested in the foam board and I am no where near done!!!! Be prepared that you may get lots of comments about the cardboard boxes not being acid free and you shouldn't store your fabric on them. I know the foam board isn't acid free but it was what I could afford. I found the comic book boards that lots of members use flimsy and most use more than one board to make the fabric bolt more stable. I'm telling myself that because the foam board isn't acid free, then I need to use it up and not let it sit forever on the board!!!
