Opening cards with cash at bridal shower?

I would probably just skip opening cards! People will understand & get a thank you card from you.

I had a few people at my shower give me cards with gift cards in them. I just opened the cards like I did any of the other cards that came with physical gifts, read the card, and said thank you - no need to mention the amount enclosed. Then write your thank you note thanking them for their generous gift.

You don't read the personal message out loud, just silently to yourself. I read the card and then said, "Thank you Diana, that was very sweet." Then she is acknowledged and the other guests understand the card was from her.

I'd open the cards, read them to myself, acknowledge who the card was from then hand the card to whoever is keeping track of your gifts. They can open the card, see the amount/gift and write it down just in case it gets separated from the card.

If there are quite a few - I'd just say "thanks for all the cards. I can't wait to open these with FH!" so you aren't sitting there for awhile opening cards.

I agree with this. Read the card to yourself, then thank the person for the nice card.

Besides letting whoever is recording what gifts/cards are from who (so that you can write thank yous and remember who got you what), you don't need to read cards aloud. You usually just tell the person recording who it's from and say thank you to the gift-giver aloud.
