I have used 300 of the comic book boards and am thrilled by the nice way all my fabric is organized. I am using them for border fabric and bindings. It is nice to have the binding ironed and neatly folded around the comic book board with the length and any extra pieces of fabric tucked underneath.
We found the cheapest place to get them is a comic book store. The clerks are really funny about all the quilters coming in to their stores now.
