I have the same problem. What I did is sort them so they go together. I have 1930, civil war, primary colors, kids prints, home decor, batik, etc. I make quilts and then add a border and or back by buying more fabric if need be. also at times I skip borders and just make the blocks go to the edge and then bind. FQ are great for scrappy quilts. If you can not make them work maybe offer to trade on the board and get some FQ or yardage of what you need.
