You can use Retique It White Wax to highlight the details and give a nice French provincial or white washed effect. Retique It White Wax is also great for that drift wood or beachy effect. A little goes a long way. Once you apply clear wax you can add the white wax then go back over with clear wax to erase and blend if needed.
