Inlaying the rosette into the top
Inlaying the rosette into the top is done by first locating the sound hole center as in the plan take your 85mm sound hole template and draw around it. Trim the rosette ends and make certain the edges are smooth. Now lay your rosette in position and go around it with a sharp knife or draw around with a sharp pencil. With a sharp knife score the rosette margins 2mm or less deep with a chisel or router remove carefully the area to receive the sound hole. When the rosette fits without forceing you are ready to glue it in.
