Doesn't save space. But I can see what I have and it saves frustration. I wrap scrap strips around boards as well, sometimes up to 8 strips on a board. I can also see what I have then. Easier to deal with. Comic book boards are not as sturdy as say foam board from the dollar store, but it takes a less space so I am going in that direction as I get new fabric.
I have a new system. 1 yard or more gets its own board. 1/2 yards I do two to a board and 1/4 yards are three to a board. Strips - as many as fit.
