Made this set of earrings and a pendant for myself.  Easy and quick to cut and combines both scoring and cutting.  Paint in various colors, I chose a gold metallic paint for this set and when hit by the sunlight it has a beautiful glow.  I also painted a set in a more traditional sand dollar color and it is equally beautiful.
