We should probably do a thread on vintage buttonhole attachments (if there isn't one already -- I haven't checked). The one that impresses me the most is the old Singer with metal coming out of it in all directions (#121795?). The result is really beautiful but there are no templates used. The Kenmore machines with the built-in driving lever are excellent. I've never had much luck with the Greist-type but I'm sure I'm doing it incorrectly.
