Wear your book – or simply a key quote. A plain quote in a cool font is $30, and a simple T-shirt design on the theme of your cover with a little text is $45. More complex projects are charged at $30 an hour, and I will estimate the timescale before the start.
I design a line of statement T-shirts exclusively for authors – Tribe of Write. Here are some of my designs (also available as bags, mousemats and similar).
