I got my Featherweight after waiting several years and sprung at the opportunity. Like my Elna (from the 80s), the featherweight is simple to maintain and I can do it myself. I did attend a Nova Montgomery Featherweight Maintenance Class last year when she and her husband went on the road stopping for several class days in Williamsburg, VA. I do have a 15-91 that is wonderful for same maintenance reason but I have decided to unload my treadle this fall as I am at saturation level with machines. Or is the fabric???
