grandetante, I started another thread on shows of presents, where lots of people had them, but sometimes in their living rooms, or in a hall a few days before the wedding, or on the wedding day itself, after the bride and groom had left.
Though I’m still in Scotland, it’s years since I heard of one, far less attended one.
Thing is, in those days ( early 70s) we got dozens of gifts, ‘ wee mindings’ from neighbours, friends, folk who worked with your mother, etc etc. As everybody has lived together before getting married, all these ‘ wee mindings’ were very welcome in those days when setting up home. I remember Chance glass and Pyrex were very popular! Everyone who had given a gift received a thank you letter detailing the time(s) of the shows, usually an afternoon one with tea and sandwiches/cakes, then a more rowdy one at night, where strong drink was served. I had three of these, and our neighbour across the way came to them all, and ate ( and drank!) her fill.
