For years & years I had only one machine. But now, I have my Featherweight, 2 Brothers, 1 Kenmore, and 3 treadles. I think it would be scary to have only one now. I use my FW the most. And oh, I forgot I have an electric Singer in a cabinet that I use for bindings because I keep my walking foot on it. I've only had the Kenmore in shop once because the reverse stopped working.
