Cross-stitch is a popular form of counted-thread embroidery in which X-shaped stitches are used to form a picture. Other stitches are also commonly used in cross-stitch, among them, 1/4, 1/2 and 3/4 stitches and backstitches. Cross-stitch is usually executed on easily countable evenweave fabric, or more rarely on non-countable fabric, on which a countable fabric is applied that is removed later, by drawing out every thread of it under the embroidery. This fabric is called waste canvas.
