I had this idea about a month ago. started playing with it on the BOC box and then took it to this mirror. One thing about JoSonja irridescent paints is they don't bet as bold on light colored woods. On black they stand out. so I masked off the mirror, cut out the squares and painted them black. Then added the paint. worked perfectly. A little more experimentation with the colors to really get the Abalone shell colors and I think I'll have something.
