A while back, I decided that I really wanted a TARDIS jewelry box. Since I was determined to make it that very day, I somehow got it into my head that I should use polymer clay. (That was the only reasonably sturdy material available to me without leaving the house, anyway.) I made the base, sides, door, top, and lid as separate pieces and glued them together. After painting and using spray on gloss to make it shiny, I glued a picture of the 10th Doctor's control room on the inside and added some plastic hooks for necklaces.
One of my favorite parts is the little blue light on the top. I bought a set of press-to-turn-on lights and velcroed the blue one to the top so I can always see inside my TARDIS box. I need to do a TARDIS jewelry box 2.0 and actually build it with wood sometime, but I felt pretty good about this one.

The finished product was about 10 inches tall with the lid on. If I make a wooden one, it will probably be about 20 inches tall, because when I make myself necklaces the chains always end up being right around 19 inches long.
First, the outside:

With the door open...

The top comes off to reveal a felt-lined earring storage area, complete with little round mirror!


This one shows the box with the light on, in a dark room.

If you'd like to see a video slide show of these images with a little recording of the blue light flashing (it can just be a steady light or a blinking one depending on how many times you press it), I did post one to YouTube.
