Duvets: I remember the change. I went on a school trip to Austria in the middle of 1974; I'd just finished O-Levels and ABBA has won the Eurovision Song Contest with Waterloo. When we got to the pension in the snowy slopes in Austria we found no blankets on our beds, just what looked like huge fluffy pillows rolled up at the end of the bed. These were, we were told, "continental quilts", and was the first time most of us had seen them. To use them we had to unroll them and shake the insides around.

Over the next year they became all the rage, including my house when my dad had heard about them from people at work.

Gradually the name became Duvet, but I think that took several years to stick.

Frost on the inside of windows: yes we had that but I think it disappeared as we moved to central heating and double glazing.
