Another registry question - gift giving

Hello ladies,
Okay so after I gave a gift credit for one friend's absurd registry, the same day I gave a gift to another engaged friend. Now upon reflection I don't like what I picked for her (although its already en route) would it be strange to pick another something closer to the wedding or something totally off her registry and just say, "It made me think of you?" I know we register for bowls and things but I think a serving bowl is quite boring!!
What do you think?

If you are truly not happy with what you purchased for her, then yes, it would be sweet to purchase something else and say it reminded you of her.

That's probably fine. She can't complain after getting two gifts!
