One of my favorite Python people recently collected all of her swag t-shirts and made quilt out them. The end result was beautiful and functional.
between that and one of my friends making tshirt pillows, I finally have something to do with all of mine that I don't wear but couldn't bring myself to give away quite yet.

Of course, I doubt my mom would be too keen on making me a quilt with the "Bianca's Smut Shack" shirt shown on Jason's site, and I doubt any protests from me about it being "a part of web history" would win.
EDIT: Failed to spell Aikido properly, again.
[Edit: OF COURSE, this being 2016, you can apparently get this done for you :-) Although it's not cheap.]
