Sorry that I haven't answered you sooner, amykitty, but somehow I didn't see your question. I saw the process on one of those HGTV shows and it seemed pretty simple to do. You might search over on their site and find the episode.
The reason I dropped back by here is because I saw another headboard alternative that I liked. Well, it's really a painting technique that might pull the attention away from the fact that you don't have a headboard. I found the picture while looking for a comforter in a particular color. The bed in the pic has an upholstered headboard, but it struck me that the room might even look better without it. What do y'all think?
