Sorting Buttons

I've never got into the popular 'adult colouring books' that came out of nowhere a few years ago. For one, it seems a waste of time - not that I'm against that in principle, I just prefer to have something to show for my wasted time. For two I never could quite get past the 'adult' part. How sad that I think that has undesirable connotations.

Anyhow, instead of filling in a colouring book, I prefer to sort buttons. Doing the colours is the most fun part. After that I might put shanks vs flat buttons together and then two holes vs four holes. By then if I have any matches I can thread them together. But I rarely get that serious, just sorting by colour is usually good enough for me. Very relaxing hobby this!
