Email Delores Pickens at
[email protected] and ask if she still has vintage ones and tested ones to sell you. She sold me vintage ones for 75 cents each - she sets a limit of 4 on those. She also takes newer ones out of the original package and tests them to make sure they work well in the featherweight, and sells them for 40 cents each. She charged me $2 for shipping 12 bobbins, only takes a check - and I received them within 4 days of sending my check to her. She'll give you her mailing address if you email her.
