I'm thinking of doing an orbital on my left ear a little above since I have my ear pierced. I want to do it myself but I'm not too sure on how to go about it. I'm thinking 12. If I take the ring, find the center of it and hold it onto my ear, take a thin marker and make a line from the ring edges onto my ear then just find where I want to have it positioned then pierce, that should work right? How do the pros do orbitals? Only on my left ear.
