I recently purchased an ordinary clipboard from Michael's for $2.50 (plus I had a 25% off coupon). I jazzed it up with some vintage jewelry and I love the result.
I only paid $10 for 2 baggies full of the vintage jewelry pieces at an antique store. I used E6000 to glue the jewelry to the clipboard. The backs of the earrings break off easily. However, a couple of the pieces fit better leaving the backs on. So, for less than $3, I have a gorgeous and unique clipboard!
