It is a slant shank machine...
Well, I found a plastic darning foot that I bought online. It doesn't even touch the fabric when the needle goes down? I am more successful at stitches to go without the darning foot. But I don't know how to get it consistently pull up the bobbin thread? I have searched and cannot find a metal darning foot for this machine...and I don't think there is a singer store anywhere nearby.
HMMM!
