On one of my latest guitars I used a simple but effective design using what is fast becoming one of my favourite techniques. The only real difference is that the wood is presented with the side grain instead of the traditional end grain. And of course the design uses the limitations of the geometry instead of fighting against it. Roses, circles, waves or leaves all have to be relatively low resolution when made with a mosaic whereas a rectangular shape fits right in to the straight horizontals and verticals.
