They are hand blown with great precision with a large bulb like bottom and a long thin stem ending in a wide mouth.
Yards originate from the days when people traveled by coach and horses.
Coaching Inns were strategically spaced along the way to provide food, drink and accommodation for both weary traveler and horse. There was a metal cup by the Coachman's foot and a crook further up where the yard could be placed without danger of falling over. Yards today come with a tall wooden cradle which acts as a display stand and resting place for the glass. Yard glasses are very expensive and not always easy to obtain, being handmade. Yards make great gifts.
