I bought a slant zig zag foot and use it for stitching quilt blocks. Makes a perfect 1/4" seam. I also bought a vintage Singer walking foot that works great. You do have to make sure and get the right foot, some don't fit the feed dogs right. Mine came in an orange and white box. The Featherweight Shop also sells new ones that fit.
Enjoy your machine, I have 3 of them, time to switch out and use my black one!
