I can’t quickly find where Jane demonstrates putting lease sticks back into a threaded warp. However, if you raise shafts 1 & 3 and slip your first lease stick in and then raise shafts 2 & 4 and slip in your other lease stick, you will have returned the cross to your warp. Secure your lease sticks in your normal way and you will be able to make changes to your warp.

I have never rethreaded a warp, but the next project will be my first. I want to do the small and large twill gamps but don't want to do two separate warps, so I'm going to figure out a way to combine the two gamps by adjusting the width of their sections and then rethreading between them. Never understood before how people managed to rethread without making an unholy mess, but your explanation is so simple! Thanks for posting.
