@Kymberly During my first attempt at overshot weaving, I learned just how much more it wants to draw in compared to other techniques, which combined with my poorer technique, meant abrasion on the edge of the warp.
Before then I was intimidated about breaking warp threads. That project I got to practice replacing warp threads at least a dozen times. So all that to say, if you get to that place and need help, ask away!
