I started making one using a remnant frame from a large art piece. Halfway thru, I realized that it still wasn't quite big enough for the area in question, so I started my search again. When I ran across this one at Home Goods, my heart sang with pure joy!!!
it's definitely a rival and was only $60--slightly more than 10% of the BD price--score! The size of the actual corkboard and the thick moulding (about 4") were just what I had in mind to visually anchor my desk to the wall. After a quick coat of white paint (the frame was originally creme), a layer of polyurethane, and a little bit of bling, here's my finished product.
Sorry I can't show you a wider view, but there's still a bit of work that needs to be done before the total reveal. Because my desk is a bit narrow, the board will be mounted to the wall sometime this week, then I'll be off to search for a new window treatment and closet storage/shelving. For now, I'm basking in the glory of this massive bulletin board--I'm in love.
