Most of my stash is stuff that my grandmother gave me out of the overflow of her stash. I either buy for a specific project or buy small amounts of fabric I like (I've been doing a lot of scrappy), generally fq or just small bits of yardage. I also have a relatively small stash and don't have the budget (or the need) to be bringing home bolts or great lengths of yardage (though I certainly see plenty of fabrics that provide the temptation! :) )
