We married in 1977 and were given two sets of bedding by my MIL. They were from Brentford Nylons when they started moving away from the horrible nylon stuff. I think they were a cotton mix. One set was purple, lilac and white and the other shades of brown and gold. We used them for years and you could not wear them out. Later on we used them for kids playing in the garden, dogs, covering stuff in the garage, as dust sheets when decorating etc.
They don’t make quality like that now. I bought some Kirstie Allsopp bedding which was thin and faded within a year.
