Thanks for all the advice! We had a similar circumstance at DS#2's wedding last August as Denise had. Our DS and his DW came over here the day after the wedding and said that they did not get a card from 2 couples that we are very close to and ALL of us saw them put the envelopes on the table. There was a "strange looking guy" walking around the reception and we later found out he just wandered in! He was escorted out :flog The 2 couples had to call their bank on Monday and stop payment on their checks which was additional $ for them. As far as we know, the checks were never cashed. I shudder to think if the envelopes were filled with cash.
Back in "my day" we rarely got $$, but I did carry around a silk purse while visiting tables for those guests who brought an envelope. Gifts were usually sent before the wedding to the bride's home and they were displayed so that friends could drop in and look them over

Actually, this was a little "past my day" but my mother was very old fashioned and wanted it this way. I like to give the gift at least a few days before because it IS a nuisance IMO to have the bride/groom or family have to pack everything up and cart it home. I think also that these days with couples living together before marriage and/or living on their own, plus the bridal shower, they have most of everything they need and $ is always welcome! (tu) I like it to be personal, tho, so I always buy something to go with the $. For this couple I had their names/date of wedding embroidered on a wedding ring comforter and put a bottle of champagne, a bag of good coffee and a bottle of Irish Cream and beautiful heart shaped "sparkly" candles in a gift bag. I'll give them a check also. I think I will make the check out to the groom and just put best wishes to Colleen and Paul in the memo part. He lives right around the corner from us, so I can drop the gift off tomorrow.
It was fun hearing about all the customs and Denise, I am sorry about your family's ordeal. Thanks again! BTW, a funny story about one of our wedding gifts: my aunt lives in CA and sent us beautiful highball/Tom Collins type glasses with DH's initials etched on the side. His initials are JOY. I opened the gift and looked at my mother and said, why in the heck would Connie send us Christmas cocktail glasses. =shrug My mother thought a minute and said, oh, those are Jim's initials; it never even registered with me. :lol Oh, and you can imagine what our house is decorated with at Christmas time! :grin
