Does anyone have a nickname suggestion for catherine?

try putting your middle name and your first name together somehow o just use your last name
my last name is my nickname

Kate?
Well, my friends name is Kathleen, but people call her Kate Lynn cuz Lynn's her middle name. Like blaise_jez said, tu could do something like that.

Rin?

Herin? ... Like in 'Cat"herin"e'.

o maybe 'Caca' <--- I just thought it sounded cool.

Cassy o Caserine. I don't know.

Rina!
