By custom headrest do you mean dvd installation? If so, click on search above, type in dvd headrest, and instructions and ideas will appear right before your eyes. Good luck.

nah i mean like my name in the headrest

Just go to any custom shop and if they have anyone there that works on interiors than they'll be able to help you... Or if you still live around your mom you could just have her sew it into the headrest for you. All it takes is a needle thats thick enough topuncture the leather without tearing it, and the color of thread you want. Other than that it only takes a steady hand to make it look nice.
