This is the completed project I was working on last week. It was a design for a ticket for an event over Memorial Day. Hence, the final format for it was going to be something you held in your hand, so I went with the flip-flop format. I've just included it here in both orientations.
Alas, it did not win, but I had a good time working on it. It brought me out of a real dry spell.
Note, while I do not really have this one "for sale", I did end up doing it out at a fairly high resolution and printing onto a 3-foot tall banner which I sometimes hang near my camp at various festivals.
