To repair damaged or worn patches on a patchwork quilt: Cut a piece of prewashed (shrunk) quilt fabric ½ inch larger than the damaged piece (on grain if possible). Lay the new piece directly on top of the old piece and pin in place. Fold under the edge and hand appliqué the new piece over the old piece. (You may have to trim the corners to reduce bulk, but be careful not to trim too closely or the corner will fray.) If new pieces abut, you may stitch them together.
