singer ultralock
Back in the day when no one had an overlock, as they were called at that time, my mother in law and I both had a singer, made in Japan, brought through the factory where she worked. It had a seam allowance and overlocked the edge at the same time. I wish I still had that machine. On step sewing was wonderful and I clocked many hours on that machine. It was the devil to thread and when it got a hair crossways, I wanted to pull out my hair, however, nothing I have had since compares.
