The comic book boards are the cheapest way to go in the long run. What I like about using them is that I can easily see exactly what fabric I have. I feel it's the easiest way to be organized.
When I first started using the boards, if the fabric was 'smallish' I would pin the ends. By the end that was too much work and it just didn't stay that well so now I just staple it. Haven't had a probem yet with that.
I even realized that I had more than one piece of certain fabrics! ha ha Guess I really liked it! Large pieces are easy to see when you fold it with the ruler but the smaller pieces aren't.
