I hardly ever mention my shop at Cafe Press (http://www.cafepress.com/insolentlad), with tees and tote bags and other merchandise with my designs. The fact is, I make more profit from that neglected shop than I do from my writing.
The big sellers? My classical music ‘joke’ items, stuff based mostly on puns. Not the work that displays any artistic ability beyond the basics of design. That’s okay, but in a sense that is me being a writer again, isn’t it?
It is true that I should work on new merchandise. I keep putting it off. I tend to put everything off and spend my time writing. And maybe that’s just as well.
