I'm at the point where the prettiest fabric would not fit in my space. The cupboards are full and unless I use some up, no new will come in.
If you plan to make a scrappy quilt, even fat quarters will yield a block. If you can select a border fabric, I would go for 2-3 yards. Don't hoard yourself into a corner. Y+Also remember that you can piece your backing so you don't necessarily need lots of large pieces.
