How to Fix a Threading Error

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
