Origami can be a very satisfying leisure pursuit for most pensioners, since it gives ample opportunities for swearing when your hopping frog turns into a fairly ordinary wrinkled serviette.

It’s also very good for entertaining small children, who can tie you to a tree or build a fire under your chair while you’re concentrating on creating a bird with flapping wings (or fairly ordinary wrinkled serviette).

Origami is Chinese for ‘fairly ordinary wrinkled serviette’.
