The weaver’s knot’s characteristics—non-slip and a quick release—are valued not only by weavers but by climbers and sailors, too. The knot can be used whenever two cords are tied together or to fasten one cord to a loom part. Because it can’t be tied under tension, it is a good knot when measuring the warp when you have a slack thread to work with. It can be tied with short ends, but not with very slippery threads, such as silk. It’s slower to work than a square knot, but more secure and smaller. So, if a square knot doesn’t hold, try a weaver’s or double weaver’s. Even so, some threads aren’t compatible enough with each other or are too slippery to tie either a square or a weaver’s knot.
There are several names associated with the weaver’s knot, such as bowline and sheet bend. I found five different methods for tying it, not including the double weaver’s knot. The method here I call the weaver’s knot with “ears”.

This is the way Jim Ahrens taught and is in many books. The worker thread should be the longer of the two. If you are using this knot to tie on new warps, the worker thread is the new warp. In repairing a broken warp, the new thread (being longer) would be the worker and the existing end would be the non-worker.
Step 1. Cross the two tails, left over right, and hold the crossing part between the thumb and first finger of the left hand. The “ears” are the ends of the tails that should stand up straight. Make the ears long enough but not so long as they bend over.
Step 2. The right end is the worker thread. Take it around over the thumb and pass it behind the left-hand ear—just the left one—and bring it to the front between the two ears.
Drop the worker. Take the right-hand ear, bend it down into the circle, and place it under the thumb so it is pinched by the thumb along with the thread already under the thumb. The bent thread is actually bending on itself and held to itself in the pinch.
To tighten, continue holding the thread bent on itself in the pinch between the thumb and index finger of the left hand WHILE pulling on the remaining end with the right hand.
