So, you know the spare buttons you receive with your garments? Sometimes they're threaded loosely on one of the tags of your shirts, sometimes included with a bit of thread in a ziplock or whatever for your jacket etc...
What do you do with all that? Leave them on your shirts? Immediately cut them all off and keep in storage for later use.
I realized I have a small collection of buttons of various styles and brands that I keep in a couple of small tins and in a way it's kind of neat. Some of my shirts I actually just walk around with the buttons still attached to the shirt.
What's your process with these priceless little gems?
