The back and sides of the body can be inlaid with various designs. The inlays are usually placed on the wide capping strip, or on the side pieces, just above the capping strip. This process is the same as inlaying the soundboard. The inlays are cut from shell with a fine jeweler’s saw, and then are placed on the body in their exact location. Trace around the inlays, and then with a flexible shaft router and a fine bit, route out the cavity to receive the inlay. The cavity should be just a tiny bit shallower than the depth of the inlay.
Glue the inlays into their cavities with epoxy or super glue. Sand the inlay flush with the body using a sanding block. If you do not use a sanding block, the softer wood around the inlay will sand quicker than the hard shell, and the surface will not be flat.
