OK, I think I'm doing ok with turks heads. I can figure out the (gaucho) on a "square" knot, i.e. 7l 6b. Watching a herringbone (pineapple) interweave video makes sense on the more "square" knots. But I haven't figured out how to adjust the pattern for a longer knot. I have a 4-bight turks head knot, I think 7 parts, that I want to add a herringbone interweave to. It is working best for me to make this knot in place, so I'm not using pins, and I'm really not having trouble with it slipping. Can anyone point me to a video, or guide, or something as to how to do this interweave?
