This box with threaded lid started with African Blackwood. The two pieces were first hollowed inside. Next, matching pieces of hard maple were turned to an exact fit, glued, and hollowed leaving only a thin layer of maple remaining. This was repeated with a piece of brown ivory wood, glued, and turned so that only a thin layer remained. The interior pattern was cut with an ornamental lathe (that I built myself). The cuts went completely through the thin layers and into the outer shell of blackwood to create the contrasting colors in the interior pattern.
