An update on my scaffold piercing (if anyone actually cares...):
I went to the place, but the piercing guy (piercer? piercist?) says the helix (curvy bit) of my ear is the wrong shape. It's too flat (story of my life), so he can't put the bar through without making my ear bend round, which would make it heal poorly, and scar. So I can't have it done.
I'm trying to come up with an alternative, involving a custom-made stud with a loop on it to substitute for the hole in my ear. It's difficult to explain, but basically, the stud can go in as normal, and then the bar feeds through the loop on the stud instead of passing through my skin. I just need to speak to the piercer/piercist and find out if its viable, and find a jewellers that can make the stud.
