A Slip Stitch is a stitch created with a hand sewing needle rather than your sewing machine. It joins two folded edges (or a folded edge and a flat edge) together in such a way that the stitches are not visible. This stitch is commonly used to close seams, such as after stuffing a pillow. It is also good for bindings, to close a lining, or to hand-appliqué invisibly. Also called a Ladder Stitch.
