Did your machine come with a parts list?
Do you have a local dealership where you can see which feet go to your machine?
You definately need a walking foot.
A 1/4 inch foot, maybe, if your machine dosnt have a setting for it.
My machine came with all the feet I needed. Its a Viking.
A darning foot is a good free motion quilting foot. I think most machines come with one. I never thought about it but maybe it dosnt touch the fabric.
