I absolutely love this idea! I'm definitely going to try making these this year. Do you know how long the cookies will last after baking? Will they start to go bad or crumble, or will they just harden and last almost indefinitely? And thanks for providing lots of pictures for us uncreative types, so we have some ideas of decorations to start with! Hello - The cookies will become very hard and stiff. They won't crumb unless you smash them up! - kelsey
