I found this heart and key tattoo from Kat Von D's website. My wife loved it and wanted it tattooed on her left foot. This tattoo was redrawn and tattooed by James @ Blue Fire Tattoo's in Chingford, London with a few minor adjustments. It's still quite dark cos it has only just been done, so it will lighten over the next few weeks. Very pleased with the results. I hope you are too.
PS: I plan to get her a ball and chain on her other ankle for when she is in the kitchen *lol*
