These ornaments are simple hand blown glass balls with a small glass loop on top to hang them up. Our standard Christmas Balls are 3.5” diameter, and are blown thin and light so they can hang delicately on a holiday tree. They can also hang in a window to catch the light, or nest in a bowl for decoration. Wave Balls and Gazing Balls are a larger, heavier version of the Christmas Ball. They are made with larger gathers of molten glass, creating a much more durable piece to hang outside and withstand wind and weather.
