Glass and crystal items are traditional Christmas decorations and gifts. Glassmakers like Sandwich, Waterford, Fenton, and others have long produced glass Christmas pieces including ornaments, tableware, wall decorations, lanterns, window-hanging ornaments, glass-beaded garlands, and limited-edition glassware.
