Thanks for the tip on the oil, I'll pick some up tomorrow as I'm going to a quilt show in another little town with my neighbor.
As I mentioned I acquired some extra feet and I tried them on the machine but didn't try sewing with them. Their shanks were different heights from the one that came with the machine so I'm wondering if I can still use them or just need to do a trial run with them to see. Any advice on the shanks?
