Thank you so much, Macybaby! I really appreciate your help.
I found a screw to fit the foot to which the hemmers attach - phew!!! I now have things as complete as they will be. I am missing a screwdriver and a stylus/pick, but that is okay.
So many of these things I just have no idea how to use - whew, gotta get sewing, to put some to good use!
Thanks again, Macybaby.
