If you've been to a display shower, how did it work out?

My sister is team green and at the same time thought we could have a 'green' theme. Like gently used baby items is fine. (ETA: she does mention in her registry how earth conscious her and her husband are. Also, it's known that she is an environmental engineer.)

My other sister and I are thinking of continuing with the green theme and asking for unwrapped gifts.

How did you/they keep gifts identified? I'm thinking of having stickers or gift tags available if they need to label their gifts.

Any other tips or advice for this display shower?

Oh, I asked my sister and she has no preference on wrapped or unwrapped gifts.
