I printed mine directly onto a sheet of grey cardstock then affixed it to the front of an envelope. That way the key could be stowed safely inside with copies of our contact info and a thank you note.
Mind you, the printable doesn't only have to be used as a way to hand over your house key to someone. You could make it into a Thank You card. It could be resized for little labels at the holidays. Or maybe you're just going on vacation and your neighbor is looking over your house.
