A number of years ago we collaborated with our scroll saw artist friend Allan Couper who did amazing work. His pieces of scroll saw allowed us to insert through the base a piece of stained glass then we used clear silicon to hold the base in place, this also allowed us to replace broken glass in the future if someone had broken theirs.
We used various colors of glass and as these Horse Silhouettes were free standing they could be reversed which provided another different silhouette view.
