I've glued up the rosette;
We're avoiding using any rosewood on this guitar which is partly why the trim is walnut and Macassar Ebony. The other part of it is the colors of walnut and Macassar Ebony happen to work great with the Maple color.
I was having a tough time finding decent Macassar Ebony binding so I got in a board with the right figure and cut my own.
One big advantage of cutting your own binding is you can easily keep the binding sticks in consecutive order so when matched up properly on the guitar it adds a nice little touch of symmetry;
The top purfling will be black and maple lines with a little touch of walnut in the middle;
