We finally finished the upholstered headboard today and put it up behind the bed. I really like how it turned out -- MamboGirl, thanks so much for the directions!!
I used 7 coats of American Walnut stain and 5 or 6 coats of a satin varathane. The finish is really, really close to the finish on the espresso furniture.
Here's a picture of the headboard....
