That must have been 5 hours of heaven! What great finds.  I'm a self proclaimed button fiend. It happened suddenly. I used to have just a teeny little pocket in my sewing box for buttons. Then I found a bag of assorted vintage buttons a few years ago and now I have two photoboxes full.  My grandmother even slips me these really awesome buttons when nobody's looking, God bless her she's a craftsy enabler.
