You might use this method when tying on new warps if the old warp behind the heddles is very, very short.
- Make a slip knot in the long thread–the worker thread.
- Slip the loop over at least 3/8″ of the short warp thread.
- Pull the tail and the standing end of the worker thread away from each other (in opposite directions from each other). This capsizes or flips the knot inside out.
- Tighten by holding the tail and standing end of the short thread between the thumb and forefinger of one hand; pull on the remaining standing end with the other hand.
Release, or undo the knot the same as with any weaver’s knot.
One word of caution from Vince Webers of Wilmington, Delaware: If you make the slip knot too tight to start with, this weaver’s knot won’t “upset”(capsize) in Step 3. He says you soon learn how much you should pull on the two threads. If you want to test this, try it with two ropes.
