What do you do with spare buttons?
After spending a lot of time over in the kitchen forum and finishing a remodel, I now realize that I need to spend some time organizing the home. One question that has been puzzling me is what do people do with the spare buttons that you get with clothes? I keep them all together on the off chance I ever need a button. However the things that lose buttons never seem to be the ones that came with extras. Also, I am sure some of the buttons go with clothes I have since donated.
Where do keep spare buttons? How do you keep them organized? How do you know which ones can go when you donate clothes?
