All the suggestions were great.
I was thinking it would be interesting for a change to have a challenge using a specific material and the challenge would be to use it to create as many different items as possible. For example if the item was a milk carton(any size), then I could photograph it being used as a bun/hotdog warmer, solar cooker, bird feeder, pen organizer, candle mold, plant starter, party favor, loaf pan(untried, not sure if it would work), herb saver.
Iron Craftster! It's perfect!
I'd be in.
