When I go to a craft event, or a pet expo, or any kind of event actually, I try to see what else the dealers/merchants/hucksters are doing with their work. It used to be just T-Shirts offered with one or maybe up to three different illustrations. Then it was carry bags. A smattering of mugs and buttons, possibly.
Well, time moves on, and what I've seen most recently were trading cards, activity books and most recently (thank you to the recent fad) coloring books. Those are hot items right now and have been for at least a year so far. It may take a bit of research to find the most cost effective way to produce these, but believe me the resources are out there.
Good quality cards (trading cards, tarot cards, playing cards, game board cards) can be made at low cost by Gamecrafter.com The quality is very good and the amount in your set, and the number of sets is determined by you not the company. Printerstudio.com is another place to check with.
Local printers can do up coloring books on the cheap. It's up to you to decide if you want a standard paper used or a thicker paper or even card stock. You pay by the page on those.
Activity books can easily be printed double sided on regular paper, folded in half (a 40 page booklet is 10 actual pages of printed stuff) and a card stock (or regular paper) cover added to it. Simple, easy, quick to run off as you need them.
And if you have images, they can be turned into paper dolls. Even jointed paper dolls. Something to think about.
