I just love my comic boards. I also use the Magazine backing boards (acid free) which are a little larger. 8 1/2 x 11 for the larger pieces of fabric. I have already used 1,000 boards and am about 1/2 way through my stash. I am ashamerd of myself however, I am a fabriholic. I am a member of the lifetime cure club but so far it has only slowed me down.
