You know that there are millions of places online to make it into a shirt.. CafePress, Zazzle, stuff like that... You can even, on Zazzle, make a private design so that if you want to be the Only one with this shirt you can..
Hey, if you have a local shirt printing shop, you could try asking there. (I know my dinky little town does, lol, because a couple of my friends work there). Something like this should be fairly easy to print, since it's only one color. It might even look better inverted, on a black shirt. You'd have to check with the shop, though. I know that ours is okay with doing small orders like this. (Small as in not many shirts.)
Wow, yeah! A black shirt is a great idea! I think we have a place where there are lots of shops for clothes that might be able to print me an awesome shirt ( LOL) Thanks for the advice, you're awesome!
