Little Genie Bobbin Washers
I bought these but I really didn't see a difference in my stitches. I then searched online for comments and found out you have to take something out of the bobbin case (spring)for them to work. I don't think I have anything like that in my bobbin case. There are no instructions on the package. I read that machines already have built in an anti-backlash design. Could any of you advise me on this. Thanks a bunch!
