For my fellow weavers: On a recent warp I struggled a lot with the selvedge, either breaking warp threads or getting wobbly results. I first tried a temple but it just doesn't suit me. So I came up with this workaround and it helped a lot. I just folded an 8" strip of narrow card stock around the selvedge and secured it with a binder clip, one on each side. I shared this already with @mloomco and she seems to like it too. If you try it yourself, let me know about your results. Thank you!
