Traditionally, in England, the couple produce a wedding present list and the guests buy something from it. These are generally household items because of the old tradition that the new couple will be setting up home together.
This has changed a lot in recent years as most couples live together before they get married now and therefore already have the stuff they need in their homes.
We didn’t traditionally throw huge sums of money at the couple, it was more that lots of people would buy things so that cumulatively they got a lot of useful things.
Recently, couples have taken to asking for money or vouchers. Some people think this is fine; some people think it’s grabby.
The bedding is a normal wedding present. The jumpers are unusual. Champagne and Prosecco is the sort of thing you would get from guests who, in the absence of a present list, didn’t know what to get you.
As illustration, when I got married in 1987, my parents gave us a set of casserole dishes and my in-laws gave us a food-processor (which we regarded as very generous as these were expensive at the time). The most recent wedding we attended was my nephew’s and we gave him £100 in John Lewis vouchers.
