How about just something sweet and personal? I think the one knee thing is kind of hollywood movieish, and your knees will get all dirty! Write a poem, watch fireworks at night, write words on a cake…possiblities are endless! As a girl though, I would want more thought involved than flashiness…think what she likes and what she would like to happen, maybe she’s the type to want bended knee? If she does, the halachic shailos are between you and your rav.
