Mandy has had her tattoo since June 2009.
What have people said about your tattoo?
"They tell me I'm brave, and if they had the courage to do it they would do it. Lots of people stop me on the street to see my Harry Potter tattoo. It's amazing to see their reaction."
Do you think you'll get more tattoos based on books?
"If I find another great and amazing series. If it has the same impact, I'll definitely do more. Books have a magic that other things don't have. Books are unique and amazing and they deserve to be remembered, loved, and respected, because books are forever."
