While you may have the patterns and theme picked out for all of the dinnerware on your registry, have you thought about your drinkware needs? If you're big wine enthusiasts, you'll definitely want to add a full collection of glasses and wine accessories. If you and your sweetie prefer spirits over wine, then make sure you add a full range of drink glasses as well as all the essential bar extras. Likewise, if you're teetotalers, don't bother with all the drink glasses you won't use. Instead, concentrate on essential everyday glasses, a set of wine glasses — they'll double as water glasses — and mugs and teacups.
