Gosh... don't throw them out... send them to ME! I'll use em!lol.
Actually, I believe that somewhere, Billy or Brenda or Char said (basically) use the metal bobbins in the all metal bobbin cases. But if you have a bobbin case that's got plastic bits, then use the plastic bobbins in that. It's a weight issue for proper tensioning I think....
good luck...
