Thank you all! Caroline, I am going to replace it. I have some batting scraps, as well as some thick felt, so I think I'll try both and see which works better. It's been in storage for a long time, so I'm afraid to use it too much without oiling and greasing it up. The only grease I have are tubes that came with machines, so I'm afraid to use that. Do you suppose it will be okay to put that in them. It's the old green tubes in the green Singer boxes.
