First time, with the asymmetry kit, I left them in because I forgot. Finally took them out when my husband and I noticed it was harder to get a good shed.
But on this one, apparently my brain was not engaged. I jumped the gun and took them out too soon. Even my husband said, “Are you sure?”
I’m going to make a check list. That worked for the order in weaving: throw, beat, change, beater back. 😉
