It started with an offhand comment in my advanced digital studio class - I told a student that I had more swords than there were kids in the room, and another replied "Ms. Young, you know what that means, don't you? You can finally have your own private army."
While not at all interested in arming my students and sending them off to right wrongs and go on adventures, I couldn't resist at least making a logo. Then the Logo became stickers, and shortly thereafter I made shirts. Now I see at least one student per day wearing my shirt and it warms my heart.
