Congratulations with your new machine. Yes, they had your bobbins in Wal-Mart. I picked these up (no.66), instead of the #15, which my machine uses.I use the incorrect ones to take with me, if I have some handsewing and I am not at home. I wind some thread on the bobbin and leave the large spools at home. I just have to make sure, that I keep them separated from the other bobbins, when I come back. Enjoy and before you know it, you'll be cruising.
