Memorial Tattoo(s)

Hey I was wondering if anyone has any suggestions.. I had two little sisters pass away and I would like a tattoo of either something they loved, or their initials/ birth/death date.. I'm not sure what people normally get in this type of situation. If you have any ideas I would love to hear them!

get anything you want that will help you remember them. this tattoo is for you and noone else. Whatever you prefer.
