Thread # 9209.01 had a mention of buttons having popped off.  I suggested button backs be considered.  Anne offered her resolve for making shanks.

I remembered the next comapny after going off line.

Banasch’s, located in OH, directs their service to the trades.  So, the items offered, among the many is button backers – both 2 & 4 eye + sew-on cloth ones – vary in the number that can be purchased.
