Actually, you can choose any name you want.
It can be
- a real name, such as "John Miller",
- a nickname, such as "My Sweetheart"
- a general term, such as "Our Family Star"
- or (referring to the binary stars) two names, such as "Tina and John".
It's your choice. There's no limit to characters, but please make sure that everything will fit. During purchase, you'll see your created certificate as a live preview. We do not do any changes if it does not fit. It always gets printed as ordered.
(In exceptional cases we reserve the right to not tolerate a star name. For example political statements or insults.)
