I don't have a button hole attachment for this machine. I am on the hunt for one, though.
I think these Vintage Kenmores are very nice machines I do like the built in stretch stitches. The cams are nice for decorative stitches. Some of the decorative stitches I would not use, but some folks might like little ducks on their creations. I am not a fan.
So the 1813 is serviced and ready for its new home.
