Oiling a Featherweight
Last Saturday, I attended a wonderful 5-hr. hands-on maintenance class for FWs at a LQS. So informative! But I was flabbergasted at how often oiling is recommended: twice while making a king size quilt (or equivalent), or once for every 8 hrs. of sewing. Seems very inconvenient, plus it's hard to believe our vintage sisters followed this practice. Any input?
