I came home from my LQS with a Singer circular stitcher and a buttonholer today. I was excited, then I discovered both boxes say for Touch & Sew machines and appear to be for ZZ machines. Will either work on my straight stitch 301? I don't think the buttonholer will, but I wonder about the circular stitcher. Does anyone have directions for either? Neither came with instructions. I think I could figute out the buttonholer, but I have no idea what to do with the other one.
