The second thread is laced through the foundation stitch without entering the ground material and without going back on itself (contrary to the comparable interlaced stitches). The foundation stitch is normally applied first, in a long line, followed by the working of the secondary thread.
Examples of threaded stitches include: threaded back stitch; threaded chain stitch; guilloche stitch; overlapping herringbone stitch; laced insertion stitch; raised lattice band; twisted lattice stitch.
