I'm glad you asked! As you might know, I'm pretty proud of my tee shirts. I don't just buy any old tee shirt and throw it on. If I don't find one that I like I'll just make one that I do. One of my favorite places to look at tee shirts is shirt.woot.com where they hold weekly themed contests and every Friday, Saturday and Sunday at 12:00am Central Time they post the winners of that week's contest. All the other days they just post shirts they like. Here are a few that I got:
I also got one for Sara: The Chemist
And here's the one I wish I had gotten... Tuesday is Gonna Be Rough
Anyway, as you might imagine I have a number of shirts. Luckily on shirt.woot's blog they showed a couple of ways to store your shirts and I went with the filing method. So far I really like it.
