BATTER UP (YOUR WRIST): The picture says a lot about this piece of jewelry. You can tell it is a bracelet made from a baseball, and, from the stitching and appearance, it is an actual, honest-to-Betsy baseball. The artist is Strle. We think it might have been great wear for Annie Savoy, the Susan Sarandon character from "Bull Durham," who always got dressy-dressy for the ballpark. Or for you, if you love the game and have built your next month around spring training. PLAY BALL: It's $45, at the Smithsonian Store.
