I bought a used Singer Fashion Mate 22C a few months ago to teach myself some sewing.
It came with this foot, which I think is a zig-zag foot which also does straight stitching.
I've been using just this foot so far. I wanted to learn some more new things, so I went and bought 3 more feet. The guy at the store asked me what kind of foot shank I have - the snap-on kind or the screw kind. I told him I didn't know as I have never changed it before. So he checked my model number in his book and gave me these feet.
Rolled hem foot:
After reading up a little, I figured out that my machine uses both snap-on and screw kind. So the zipper one fit fine (it was a snap-on).
But I can't attach the other two (gathering and rolled hem feet) because I think they are the screw on kinds, and I can't remove the shank after removing the screw:
The shank is too tight. I applied some machine oil and used all my strength to get it off but it's not budging. Is it because its an old machine? How do I get it off so that I can attach the other feet?
