Keep wine where it belongs - in your guests' hands - by tagging their glasses.
Parties can put a strain on your wine glass supply. Once you've rounded up enough glasses for every one of your guests, people have a habit of misplacing their drink halfway through - and then coming back to the bar for a new one. Prevent wine glass waste (or making people drink out of coffee mugs when you run out!) by buying or making a set of labels so each drinker can always spot his or her own glass.
If you're in a pinch, using holiday gift tags and string will do the trick. Otherwise, here are some of our favorite picks:
