The hand blown lampwork glass ball is made out of borosilicate or boro glass and surrounds 5 blue and green feathers. I can customize this ball to put the number of feathers in to represent your family members. Just send me a note with how many feathers you would like me to include in the ball. This is a handmade piece of glass art created by me, Kyle Keeler. The glass ornament also comes with a story I wrote involving a Carolina Wren. You are purchasing an ornament similar to one seen above. There is more than one available. The inspiration for the feather ball came from an experience I recently had with a Carolina Wren. In February, I took two months off to remodel my kitchen. Upon returning to the studio I discovered a wren had built a nest in a container on a shelf in the corner of my studio. THE SYMBOLISM OF THE FEATHER BALL The feather represents a dream or goal that you have and the clear glass surrounding it represents the importance of seeing that dream every day and protecting it, until it can fly. I invite you also to find your own interpretation of the feather ball. Diameter - around 3 inches I guarantee all my work and want to ensure customer satisfaction!
