Here's the finished piece, shellaced and oiled. I usually screw up a piece when I finish it, but this one turned out ok. I used a 1lb cut of shellac as a sealer, and did a fine sanding with 400 grit. As soon as the shellac went on the walnut really popped. Once the shellac coat was sanded, I applied a coat of Danish Oil. The walnut really came alive. I followed the Danish Oil directions from a Fine Woodworking article, wiping off the excess that seeped out. I ran out of time and had to let it set for a week. The next weekend I applied another coat, again following the Fine Woodworking article directions. This is the result of 1 coat of shellac as a sanding sealer, and 2 coats of Danish oil.
Now all that is left is to apply the shade. I'm not 100% sure how I'm going to do that yet. As of right now, my plan is to cut a piece of material to fit each of the "4 frames" and place the material in the frame without glue. If I have to use glue I will. Any ideas on what material to use or how to attach it would be appreciated.
As for the pictures, I'm no photographer. I do know that over a distance parallel lines will look somewhat curved because of the curvature of a camera lense. So, the curve effect in the full length picture is an optical illusion. Another optical illusion is the bottom stretchers. The angle in the picture is just weird. If there are any other mistakes in the piece, those are optical illusions as well :).
