Years ago, my husband inherited several pieces of vintage costume jewelry from his grandmother. He was very close to his grandmother, and because her jewelry has such sentimental value (and it's pretty to look at) he chose to display it in an old, wooden case. There are several brooches, a pair of earrings and a cocktail ring.
Our bungalow has its original picture molding, and we use it to hang artwork and mirrors using picture rail hooks and braided wire (fishing leader material). I love the old-fashioned look of hanging pictures this way. It also means we don't have to put holes in our plaster walls!
