This jack-in-the-box is in the baby's room of Pam's dollhouse.
I made this piece a number of years ago. The teddy bear in the box is made of Fimo. The box itself is cherry wood that I cut on my old Dremel table saw (which I wore out completely over the years).
The B on the front of the box and the raised wood on the edges surrounding the B help to give it an old-fashioned building block appearance. (I used my jeweler's saw to cut out the B on the front.)
I used watercolor paint to paint the toy horse on the side of the cube. There's a picture on the top, too, although, where it sits in the dollhouse, no one ever sees it. I added wood stain over the top of the watercolor painting, which gave the piece a somewhat aged appearance.
I mounted the bear on a toothpick and then inserted the toothpick onto a ballpoint pen spring. So, if anyone ever picks up the toy, the bear wobbles inside just like it would in a real jack-in-the-box. However, I didn't make it so that the bear pops up out of the box. The lid is permanently ajar.
(By the way, if you click on the photo, I think you can get a much closer/larger view of the box. This Web site works that way on my PC, at least.)
