My stash is mostly fat quarters. I love scrappy quilts, and fat quarters are great for them. One FQ can end up in two or three quilts and still have some left over for the "official" scrap bins. I do buy yardage of good background colors (neutrals, solids, grunge, low-volume) and occasionally of a fun print that will make a good purse or tote bag. I have bought other pre-cuts for specific projects, but for my use, FQ are the way to go.
