F, W, & B. Nice auction, but I wish there were bunches of buttons, too many to count. I need them for a closure on the strap on my sweet new husband's tracheostomy bibs that I make for him. He is celebrating 10 years cancer-free, this year. In fact, just passed the 10 year mile marker, recently. We are so GRATEFUL!!! Happy day everyone! -EJ =DDD
