Not much detail I'm afraid!
Im looking for a children's book I read about 30 odd years ago, but may have already been an old book at that point.
The only detail I recall (and it haunts me every year or so!) is that there is a reference to paint blisters on a (green?) shed door at the end of the garden and the blisters maybe look like animals?
Really not much to go on but for some reason that flashes up in my mind every now and then and I wonder if anyone knows what I am talking about!!
