When I first started out, I got the bolt cardboard from my LQS. And they looked so pretty. I arranged by color unless it was the same line. This went on for awhile then......I ran out of room. Spent a whole week getting them off the bolt boards and used my 8 1/2 X 12 ruler method. I was so suprised how much more room I had left. Those bolt boards take up half an inch of space and when space is at a premium, this worked much better for me. Now I have different ways to fold fat quarters, half yards, 1 yard, then yardage. Everything is marked with the amount of yardage. And the ones I have folded different, I can tell by looking and I have them all separated. Now, if I could just get the other side of the room organized...............
