This is a true challenge-but fun. The small Cabochan Hexagon necklace comes complete including EZpiecer hexagon templates. All you need to add is a needle, sewing thread and time. The small cabochan is antique brass and measures approximately 2-5/8" from edge to edge. The opening is approximately 25mm. These would also make lovely Christmas tree ornaments. We've given you an option to just order blank trays as well.
