Is there a more January task than carding buttons one has cut off of worn-out clothing so that they can be re-used? If I didn't sew some of my own clothes, and if I didn't hate shopping for buttons, and if the outside temperature today wasn't well below freezing, I'm not sure I'd bother. The only way I've found to keep track of these salvaged buttons is to sew them onto small rectangles of cardboard, cut from tablet backs that I keep for the purpose.
You can never have too many sets of white buttons. I think these came from a much-loved LL Bean shirt. Their clothes typically have nice buttons and I like the pie-crust edging on these.
