If I was ever taught this, I don't remember it. I KNOW I was taught that there are "no knots in embroidery" ... so, I learned several ways to fasten thread for needlepoint or cross stitch .... but, for hand sewing (hexis for me) this is brilliant!
The Trilene Knot is a strong and reliable connection to be used in joining monofilament or fluorocarbon to swivels, snaps, hooks and artificial lures. The knot is said to retain 85-90% of the original line strength. The double wrap of line through the eyelet provides a protective measure for added safety.
