Production Decisions.
In order to keep my doll clothes fairly priced, I continuously work on my production flow. Yet some steps just need to remain. I could sew the waist elastic on the serger, it would save at least 10 minutes per pair. But it would make adjusting or exchanging the elastic impossible in the future. I could also knot the elastic, but I choose to pin and sew it to eliminate a hard bump on the doll.
