Small late 60’s/early 70s children’s book- I ‘think’ it was about quiet cozy things to do, but I especially remember a picture of a snail outside in a light rain by pebbles and I think an upside down pail in one picture. I’m pretty sure it was watercolor illustrations. Sorry so vague I was quite little and my grandmother used to look at the book with me.
It’s a long shot, but could it have been Things To Make And Do, in the Ladybird series?
Could it have been The Quiet Noisy Book by Margaret Wise Brown?
