I use lots of different feet for my Singer. Depends on what I'm working on but for piecing I use my "little foot" which is a plastic 1/4 inch foot. Makes life way much easier. I still have to measure every time to make sure, just my nature to 'make sure' lol lol
If you have Singer parts...........I have a hand crank singer that I need a bobbin case and bobbin for. My sister bought it 'as is' at an auction when she was living in Scotland with her military husband. It's in the original wooden case and all. I love it and keep looking everywhere for parts to it.
