There are 3 or 4 different Singer Touch and Sew bobbin cases. Make sure that you buy one that is specific for that machine. If you want to make sure that it does the stitches, just make sure that the machines needle shaft can move side to side, like a zigzag. Put the machine into the stitch that you want to do and put a stiff piece of fabric or sheet of notebook paper under the pressure foot. after setting up the stitch, width and lenght, turn the hand wheel FORWARD not backwards, and make the machine work thru the design.
Good Luck....
