I'll buy a yard or so of a fabric I fall in love with even tho I don't ahve any plans for it when I buy it, if I can afford it at the time. I seldom buy fat qtrs unless it's "just perfect" and I can't find any yardage of the fabric. I don't do that very often tho, that can get expensive fast. I haven't bought any jelly rolls...yet. I've been using what I have in my stash when I need that size for a quilt.
