This bookmark is part of my Celtic artwork series. This bookmark is made of a spearmint green glass enamel fused onto a copper base. It is enameled on both sides, with at least 2 coats of enamel per side. Once the green color was fused, I added the dark brown circular Celtic knot work pattern. It is attached to a brown leather strap with copper wire. The enamel piece is approximately 1 1/4" square, and the entire bookmark is about 6 1/2" long.
