Another Dr. Who fan is born! I was a bit dumbfounded that you'd never seen ANY of the series, but then Dr. Who has never really penetrated into American culture the way it did in Canada and the other countries that are more closely tied to Britain. People often identify themselves by which Doctor they grew up watching. (I was a Tom Baker kid.)
You picked great stuff to put into the box, even without having seen the show yet! I love the idea of using the bottlecap as a necklace. I might take two of the ones you sent me with the Potholder Swap and make cufflinks out of them!
