Weaver’s knot tutorial - an important join to know. Very useful for knitters and crocheters. I actually use this knot to join thread on my serger but never thought to use it for knitting or crocheting.
Ultimate Knots The Non Slip Loop Knot. The strongest loop knot you can tie. Used by big game anglers worldwide. Easy to tie, far stronger and more reliable than the old fashioned strangulating figure eight knot that can substantially weaken line.
