I'm trying to sell prints, shirts, and charms, but I don't know where to begin. I've made a shirt, but they haven't been selling. All the test charms I've made look awful; they're all wrinkled and bubbled, and they always stick to the aluminum foil so I can't flatten them without imprinting the texture of the foil.
I'm trying to look for a convention to rent a booth at to promote my artwork and start a following, but all I can find is Comic Con. I've applied, though the bar's really high.
Any advice?
