Make Sending Thank-You Cards Easier
During the excitement of a shower, it can be hard to keep track of who gave what. Have a helper write the givers' names on labels, and stick them on the box right after the bride has opened it.

I was at a shower this past weekend where the sister (note-taker) had printed a list of all of the guest names so she just found the name on the list and wrote in the gift they gave the mom-to-be.
Better yet, use labels with the guests' addresses so the bride doesn't have to look them up to do her thank-yous.
