BM gifts

Is a pretty 3 piece jewelry set to wear the day of (and it's neutral and pretty so they can actually wear it again) in addition to a manicure gift certificate and a nice card a good gift for my girls? ....and i'm going to get pictures of me with each of them individually at the wedding and then put it in a frame with pics of us as kids (but they obviously wont get that til after the wedding)

Is that enough? If not, what else could I add cheaply?

I think that is great, and I LOVE the idea of the picture frame with you guys at the wedding and when you were kids - what a thoughtful gift!
