I should try them, too. Wonder if my LQS has them. Thanks for the info.

Sure glad I searched the bobbin washers information. Was trying to figure out how I could get just one teflon washer to try it without putting out the money. Now I do not have to; have found out a lot about the bobbin....thank you!!

I sell tons of them. Both sizes. People really do swear by them, especially the thread play folks!
