The Appliqué Stitch is a stitch used in appliqué work to attach one material to another.
In reality it is a kind of buttonholing, but beginning from the left hand side, and worked towards the worker, whereas correct buttonholing is worked away from the worker. The latter stitch makes a knot, which Appliqué stitch avoids. The stitch is necessarily worked very closely over the raw edge of the appliqué material, to avoid fraying.
