Introduction:
There is a whole chapter of knots in my book Warping Your Loom & Tying On New Warps. The knots here are from the book.
Surgeon’s Knot
This is the knot I usually use when tying 1” groups of warp on to the cloth apron rod. It’s fast to make, easy to adjust and has more bite than an ordinary knot.

Tie the beginning part of a shoelace knot, but before you tighten it, while the knot is still loose, take the tail you were working with into the loop and out once more. This gives the knot enough bite to hold, yet be adjustable.

Tighten the knot by pulling the tails in opposite directions. To adjust the warp tension, pull on one of the tails, and the knot capsizes or loosens. Hold on to the tails and pull the knot away from you to tighten the warp, then pull on the tails to tighten the knot down again.

Finish the knot with a half-bow knot as shown in the illustration.
Half-bow Knot
A half bow is a bow (shoelace knot) with only one loop. It is very fast to tie, secure, and pulls out with a jerk. Use it anytime you’d use a bow but want to make it faster and easier to pull out. I use it to tie the crosses when warping. It also can be used on top of a surgeon’s knot when tying the warp onto the cloth apron rod.

1. Tie the beginning of a shoelace knot.
2. Make a slip knot on top of that: First make a loop by crossing one of the tails over the other. Then reach through the loop making another loop within the first loop. Remember, don’t pull the tail completely through but make a loop instead.
3. Tighten the knot by pulling the loop and the other tail in opposite directions.
4. To release the knot, pull on the tail that made the loop (usually the shorter one).
Weaver’s Knot
The weaver’s knot’s characteristics—non-slip and a quick release—are valued not only by weavers but by climbers and sailors too. 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. A splice knot is good then, or Jim’s fisherman’s knot holds the most slippery threads.

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.

2. The right standing 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.

3. 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.

4. 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 standing end with the right hand.
The key to knowing you’ve tied the weaver’s knot correctly is to be able to release or undo it. To undo it, you want to straighten out the thread that makes the “U” in the completed knot. No matter which way you tie it there is one thread in a U-shape and the other thread winding itself around the first. Pull on both ends of that “U” thread—in opposite directions—to unbend it and straighten it out. The squiggly portion can be slipped right off, and even the squiggles relax so you have two fresh threads when you’re through.
