I am in the process of moving from ruler folded to comic book boards since I kept messing up my stacks when I was auditioning fabric. Since 100 of the comic boards is only a couple of inches thick, I think the little bit of space they take up will be worth it since I won't have as much of a mess when I pull fabric out and try to replace it where it was (my fabric stacks seemed to expand when I removed fabric from it
)
