Iron-on patches. I design and make them myself. I have a lot of patriotic and military-themed designs that I think would sell really well there. The patches below that I designed were actually inspired by the S&W forum, and since they are an affordable impulse item, I am hoping to sell a basketfull at the SJ gun show. Maybe it will be a bust, but I really want to try. I sell these by the boatload online but this will be my first foray into setting up a live booth.
