I used the 301 foot controller today and the Featherweight just hums right along. Makes that pretty straight stitch that these old machines do so well. My husband is going to take it out to Kimberly's in Katy this week to have them over it. After the mess the wiring on the controller was I don't really want to use it much until someone looks at it. I told my husband I was lucky I didn't get burned from bad wiring in the plug.
