I have a 1948 Singer 66-16 which I am thinking of getting fixed up to use for machine quilting since there is so much more room than on my Bernina. But, as far as I know, there is no way to drop the feed dogs. Is that something I could get a repairman (or woman!) to put in for me? Or should I just focus on ways to cover the feed dogs? Thanks for any advice you can give me!
