Happy sewing :lol:

Thank you one and all for the information. You have thoroughly impressed my DH. Now to learn to use these items as soon as I get the machine cleaned up and a place to put it. I just can't believe that I have let it sit for years in the storage building. And I'm supposed to be getting my grandmother's treadle that she learned to sew on.

#6 is a gathering foot. crazy looking, but it works.

I hope that you have many happy hours of sewing on grandmother's treadle :D:D:D
