Little by little I've been organizing my fabric by folding it around magazine and comic book backing boards. Certainly not my invention, many have already done this and I finally jumped on the bandwagon. I'm going through all of my cubes and doing a container at a time so I don't get wiped out and give up. I use the magazine size for pieces over 1 yard and the comic book size for 1/2 yard - 1 yard pieces.
Here's an example of what the cubes look like before and after the update:
It's so much easier to see what I have when they're folded this way on the backing boards. When they're in stacks I can only see what's on top, so this will make searching for a particular fabric so much easier. Now on to the rest of the cubes!
