DIY: hand-painted tribal T-shirt (on etsy)

Here I was about to donate this great 1990s cream-colored mesh T-shirt, then I realized I could paint the opaque cotton portion in the front.  I decided to paint tribal-looking hash marks, alternating between thick and thin marks.  I used black fabric paint from Hobby Lobby, and a thin paintbrush I happened to have.  It took about 3 hours, but the time flew since I was watching a film (of course).  It's relatively simple; I just eyeballed it as I went along.  This is currently for sale on my etsy store.
