I make a lot of t-shirt quilts and like to put a colorful border around each block. For that it usually takes about half of a fat quarter, so I stock up on a variety of fat quarters whenever they go on sale at JoAnn's for 99 cents or less. I've also bought several charm packs, layer cakes and jelly rolls from Missouri Star Quilt Co online, but haven't gotten around to using any of them just yet. When I find a good sale on fabric that I think would look great as the back-side of a baby quilt, I'll usually pick up 2 yards of it. I also like to use my 50% off JoAnn coupon to buy 8-10 yards of fabric that I know will be good to use as sashing in just about any quilt.
