I'm glad you did this challenge. It's a technique I've wanted to try from the first time I saw Auntie Clara's posts about it. Unfortunately for me, November/December turned into a time of mourning and soap challenges just didn't happen. I did manage to try it, and will again later this week. The fact that it became part of the monthly challenges was part of the reason I even had the confidence to try it.
Too difficult? I don't think so, as long as you keep your oils and lye waters straight.
