OCD, thorough, or methodical?
Organization of swatches can be a serious issue. I have a huge number of them, hundreds maybe, and some that I can't match up to charts which is really dang annoying. So here's the new and improved method. I've been using these swatch tags for a couple of years, and now I'm also printing out a small version of the chart as well as making space for a clipping of the yarn used (not shown, but it's attached to the bottom of the tag) .
I print these on TerraSlate "paper", which is actually a waterproof and rip-resistant laser-compatible archival base.
