When I was getting my piece ready to send to China, I cut one of the threads holding a string of swatches! On top of that, the thread was made of monofilament or slippery fish line. I had to reconnect the thread without extra thread for a knot and besides, it couldn’t show. It was one of the purple strings beside the black one.
I don’t think I’ve ever used this knot before but I’m sure glad that I remembered it when I needed it. The knot is Jim’s Fisherman’s knot which I learned from my mentor, Jim Ahrens. It’s for tying very slippery threads together. I put it in my book, Warping Your Loom & Tying On New Warps, available now in print after being only available as a PD for many years.
How to tie this life-saving-knot-for-me is the subject of a post from quite a while ago. The post gives full directions and hints. The link to the post is HERE.
