, generally, yes. We didn't have one, and I've not been to one before, but I'm pretty sure a gift certificate somewhere.

Unless they've already done a registry?

a bottle of champagne

ooh yes, wine or champagne would be nice. Maybe a nice little gift basket with that, fruit, cheese and crackers?

thanks! I have no idea of the etiquette for these things. I'll do a wine and cheese basket

I know they were out working on their registry recently, but isn't that solely for the wedding?

some people buy off the registry at engagement parties ...

others just buy something else random. People brought us stuff like champagne glasses and punch bowls

We didn't have one, but friends had registries up for the engagement. And, my SIL's standard is a gift cert to Bed, Bath & Beyond
