I have found that I'm better able to use up my really small scraps (and I keep stuff that's 1.5" square, even) when I sort them/store them by colour. If you've got the time to start a project right away, maybe pick a few colours that could go well together and just focus on getting those out of the drawer and see what you can make from them. 9- or 16- patches are easy, or fence rails if you've got strips, and I really like tiny hourglasses for the bitty-bits.
