Carpet Stitch is a term sometimes applied to varieties of Cross Stitch or stitches such as Cashmere Stitch. It also is applied to a Rug stitch worked with a crochet hook and thick wool.
To work as in the Rug Stitch: short lengths of wool are cut; each length is folded into two; a crochet hook is inserted in the loop thus made at the fold, and the fold drawn through the canvas from the top surface in and out again to the top a thread or two further on. This is half the stitch (see Illustration (a). In the other half the hook catches the two loose ends and draws them through the original loop (see Illustration (b). All the loose ends thus come to the surface of the canvas, where they can be fringed out to give a matted appearance.
