A few people asked about light. I knew I wouldn't be able to rely on window light alone, so I installed a daylight balanced florescent light directly above (to avoid glare) my easel. Today was a drizzly day, so without the light I would have been working in the dark. In this photo (below) you can also see my shadow box with both lights that I mentioned yesterday.

Below is another closeup of my shadow box - in use. You can see the spotlight on the left (in a regular light fixture, attached to a long, bendy arm ordered from B&H). And the real white light attached to the pvc on the upper right.

Here is a close-up of my real white light, pointing up towards the white cloth and bouncing around a bit inside my box (no direct light). I've taped it so it stays in this UP position. And I use a "north light filter" from my buddy
Qiang over the light to make it even more blue, because I like the effect on my setup.

A couple of you asked how I attach the wood to the tri-pid. (the shadow box sits on top of this wood - I don't have the box itself attached to the tripod) Hopefully the photo below explains itself. The black part came with the tripod, with holes in it, which worked perfectly to screw the wood on.
Lots of you have suggested my husband make a kit for this, but at this point he has no interest, sorry. I have suggested he make a pattern, and he may do that if I can talk him into it. I'll post about it if he does.
