Minimal with escort cards, money box and guest book. Head table was was minimal too with champagne flutes and small hurrricane lamps.
Honestly. as minimal as possible. we will be having a long rectangle table. my decorator is probably putting a sparkly tablecloth. or runner (i'm leaving it up to her). our card box and if we do a guest book of some sort (currently we are thinking of a wood sign to hang in our house after). maybe a framed photo of us. and then there will be a small section at the end that is a memorial table. which will have a framed sign about those who can't be with us. and some photos of them.
I haven't bought anything yet - so it may change, but right now I would have one table for the receiving table as for the guest book (even if it's not a book technically). And then like Stephanie said probably a picture of us if that isn't incorporated in the guest book. Other than that maybe a table runner that matches our colours and some tea lights.
