Creative Use for Collection of Hotel Key Cards?

Good Questions

Q: I'm in the process of creating a nursery and I have decided on a travel theme. I work for an airline and my husband works for a space company. I don't want to go overboard and do too much in the room. I have something though that I would like to use but need some creative minds to help me find a use. We have been collecting hotel room keys as long as we have been together and have probably 200 of them. Can you suggest anything that I can create using them? And if not in a baby room somewhere else in the house instead? Thank you!

Editor: You have a ways to go before you can do what Holiday Inn did last year when they built a pop-up hotel room in Manhattan with 200,000 key cards! Readers, what clever ideas do you have for Marietta?
