Have you ever threaded a warp, started to weave and then discovered that you have made a threading error? in the middle of the warp? Do you undo what you have woven so far, and rethread your loom (muttering a few unspeakable utterances as you do so?)
An alternative to rethreading, especially if the error is near the middle of a +700 end warp is to use replacement heddles, tied to the correct shaft. In this particular example, I have incorrectly threaded a pattern sequence, repeating it once too many times – in the middle, of course.
The offending threads are on Shaft 3 and should be on Shaft 1,that should form a section of tabby between blocks of Bronson Lace.
- Find the threads that are going to be moved to Shaft 1 from Shaft 3 and mark them with a coloured thread.
- Cut lengths of strong cotton yarn for the replacement heddles, making them long enough to wrap around the Shafts with allowance for tying.
- Find the correct location for the replacement heddle on Shaft 1
- Use the existing heddles as a guide to the correct placement of the eye of the heddle
- Tie a square knot, aligning it with the bottom edge of the eye of the heddle
- Bring the 2 ends of the new replacement heddle around the warp thread that you are correcting
- Tie another square knot to form the top part of the heddle eye, aligning it with the top of an existing heddle
- Bring the 2 ends of the new replacement heddle over the top Shaft and tie securely with a square knot
- Untie the warp thread that you are fixing, from the front apron
- Remove it from the reed and from the incorrect heddle on Shaft 3, leaving it threaded on the now corrected Shaft 1
- Rethread it through the reed and retie to the front apron
