Need help from the crafty types..

I'm in process of improving the desk that's going to go into my study. That means a nice new coat of stain, new hardware, and a painted design on the doors. My problem comes from the design.. I thought I could transfer the design to wax paper and then us a lamp to shine it on the door, then paint it, but it's not working (that is, the design isn't showing up). I can't cut out the design and make a stencil. I *don't* want to do this freehand. Any ideas?

I hate, hate, hate not having any good craft stores around here. ::grumble::
