I have some alphabet photography at home and I always thought they were really neat, but simple. It has become very popular, but instead of paying money to order it online, readers can easily go out and make them themselves. In alphabet photography, all they do is find letters in nature or objects and join them together to make words. Online when you order one, you can create whatever word you want and you can choose the design of your letters, but of course they charge you by the letter so it can become expensive.
