Your artist may happily draw for you ahead of time when you have COMMITTED by leaving your $100.00 DEPOSIT and setting your appointment date.  If you're simply dying to see your design early, kindly let your artist know.  In most cases, your design will be ready and waiting the day of your appointment.  Any changes can be made at the time of your appointment.
Some artists will draw directly onto your skin with a marker.  This is called "FREEHAND" and is done at the time of your appointment, of course.
