Advertising is on clothes! I advertise my primary ( isn’t that what WordPress calls it? ) blog GRACE PARTAKERS on a baseball cap! I’m thinking of DooRFrame Books either on a cap or a tee. Probably not much ‘bang’ for the buck, but handing out ‘business’ cards doesn’t appear to work well either.
Begging people to buy a novel is rather lame, too.
So, hat or tee?
