I decided to try the boards -- I prefer the magazine boards to the comic book boards because they seem sturdier -- I cut the comic book boards down so I use them for smaller pieces of fabric. Unfortunately, my shelves have a railing about 3" up and the shelves are not adjustable so the boards are awkward to get in and out. I had all of my fabric ruler folded and that worked better. I have to re-think all of this.
