Make 2 circles one smaller then the other send the larger one to the back and the smaller one just in front of that. This will be cut on path and with tabs to cut out the final project. The inner circle should be set to 0 depth for cut Larger circle should be the same thickness as the material you are using
Before i did any cutting i painted a peace of MDF white and covered it with painters tape. i tapped in one direction with about 1/4 over lap. thin i rotated my peace 45* and repeated. this will make it much easier and much faster to get the 2 tone pain done. once the peace is done cutting take a hobbie knife to trim and fix tape where needed. paint the other color of your liking. i wanted mine to look like a peace that has been through a war and battle.
