Nancy uses square knots to create string heddles so you can weave on your inkle loom. The loom in the video is a Schact Inkle Loom but we carry a wide variety of inkle looms at The Woolery. Inkle looms are designed to weave several yards of narrow fabric for articles such as belts, sashes, ties, bookmarks, hairbands, guitar straps, etc.
