Hello strong, bitchy here again. Have name changed.
Okay, so most guests choose off the list which was basically a Denby dinner service for 8 with plates, bowls, mugs, serving wear. A cutlery set, a full set of quality glassware including red wine, white wine and champagne glasses, napkins and placemats.
We also got maybe £300 of John Lewis vouchers total from 4 couples which we put together to buy bedding.
£300 cash total from another 4 couples which we spent on extra treats for our honeymoon. We used this for a day trip, an upgraded meal at the AI hotel, an expensive bottle of fine wine on the first night, and gave $50 to the guy responsible for topping up our mini bar LOL.
Offlist gifts...
A beautiful painting of our wedding venue which we had framed and is one of my favourite possessions.
Gorgeous silver goblets which sit pride of place on our fireplace.
A set of wine glasses (but haven’t quite used yet as they don’t match the ones from our list.
A le creuset coffee maker and a lovely smelly candle.
A set of le creuset pot holders (used every single day for several years now!!)
A bottle of wine from the year we met. We shared this on our first anniversary and have kept the bottle for a candle holder. Loved this gift!!
A very classy silver picture frame (just the 1!) which we used to place some wedding photos in.
A horseshoe from a baby guest. Apparently this is traditional. It was so sweet and it hangs in our kitchen now. 
A restaurant voucher to an amazing romantic Italian place.
Another couple took us out after the wedding as their gift for a Michelin star meal and spent £800 for the 4 of us. 
Hope this gives to an idea. We were so grateful for everything that was given.
I would say you should do a list. It’s a social contract that can confuse guests if you try to avoid it. It works like this...
You invite guests to join you to watch your ceremony.
In return you thank them by providing a reception with food and drinks.
To thank you for the reception most guests will bring a gift.
Just don’t mention it on the invitations if you don’t want to be too pushy.
