Have you got a cut out face design in your inventory? From what I understand it won't take just any pattern.
Scanned from QR codes then? I know that you aren't allowed to display designs made by others in the Able's shop... maybe the same applies here? Maybe there's a way around it, but I'm not sure. But that would be silly, because then why would they even allow QR codes to be made for these? Ehhh I'm stumped.
Nope, gates are not open. I did scan them from a QR code, but I don't see why that would be a problem.
