I also use the comic book boards for my fabric. Yesterday I got started reorganizing them again as I'm running out of room. I found I have fat quarters and 1/2 yds. on boards so I removed them. I used to have them sitting upward as your photo shows but I find I like them better sitting lengthwise so the boards don't bend. My shelves are the perfect depth that I can push the boards to the back and they'll stick out just right for me to see what I have. The top shelf I'll have to keep standing up as I'm not tall enough to see over them. Still working at organizing them today. Can't wait to see how yours look when you're done. You'll feel a big accomplishment when you're done I'm sure of it.
