Light-Up Greeting Card?

I want to make a card that lights up for my boyfriend this Christmas. I know how to make a simple circuit that includes a 3mm LED light and a button battery. Adding a simple paper switch in there is not difficult either. However, I do not know how to make the switch work when the card opens and closes. Can someone kindly send me a site, diagram, or explain to me step-by-step on how to make a switch in the card? Thank you so much.

light a candle and put it in the card - then put it under the very flammable Christmas tree
