I had a pile that looked very much like that. I sorts first into sizes. Anything under a half yard was considered a " scrap " and went into one pile. Then I sorted the rest by color. I know that lots of people use the boards to wrap fabric, but to me that's a waste of time to refold and wrap, and money for the board. Just fold it. Then put the sorted colors in the storage of your choice - I use clear bins, but you could use shelves, bags or whatever, depending on how much you have. I have a container for WIP's ( works in progress ) and sets of fabric that is already coordinated, so I don't accidentally use a key piece of fabric in another project that in one project that I was already part of a set. Just pick away at it and it will eventually get organized!
