For Emilia’s No Philosophy website we needed to create thumbnails of t-shirts with prints. This required a t-shirt outline, preferably in vector graphics, that we could use freely. After searching the net for a while, still no luck. So, courtesy of Emilia, here is a template that we ended up creating ourselves, free for you to use. It is hereby released to the public domain. Visit the No Philosophy website to see it in action!
For the curious: we created it by scanning a hand-drawn image of the outline, reducing the size greatly with Gimp (to eliminate detail) and tracing that bitmap with Inkscape.
