We are often asked to suggest an alternative to the traditional guest book and I love this example from Personalized Prints on etsy. Each leaf is a signing spot for guests and the trees come with different numbers of leaves for small or big weddings. The turnaround is quick and as you can see, it's pretty enough to simply hang on your wall (as I did for the Wedding Library poster I commissioned). You have the option to print it yourself, too, and for different quality printing. Fun, decorative and novel. I love this guest book idea!
