Ways to sell photographs outside of IG and traditional prints (Hobbyist)

Outside of paper-prints, what are some interesting ways to sell your photographs on a !small! and non-pro scale, such as printing them on a small piece of wood, which in my town, EVERYONE does during flea markets. Is there another idea?Postcards sound cool but you would have to order them online, and I dont think you could make a real profit, am i wrong? via /r/photography http://bit.ly/2GW14Sl
