I read this to my son when he was little. I can't find it now, may well be in a box in the cellar. As well as I can remember is:
Fairies live at the bottom of the garden, in this old flowerpot.
They are busy every day:
putting dewdrops on flowers
teaching birds to sing
looking after new plants
? now the sun is setting ?
goodnight garden fairies
I bought the set of 3 or 4 fairy stories, one about rainbow fairies, I can't remember the others, from Safeway in Wembley Park, about 1985.
