Recently I tied a new warp to an old one. The directions to do this are in my Book No. 2, “Warping Your Loom and Tying On New Warps“, Chapter 8–”Tying on New Warps.” I had forgotten a few of the nuances, so re-reading my own book proved to be very helpful. It saved a lot of time, tangles, and trouble. How to tie on new warps had also been a previous tip.
