Swimming cap bags

Not only for parents, but darned useful nonetheless, are these little bags made from old swimming caps. You know, the highly-textured, rubberised ones old ladies used to wear, and now some young funky folk sport in a cool-stroke-ironic fashion.

Swimming caps keep the water off, right? So they are perfect for keeping anything squidgy, liquid or messy away from the other contents of your bag. I'm thinking, half-eaten apples, licked lollipops, even a dirty nappy at a push. In fact, I'll bet this is one of those items you find a million uses for once you've got one, and then you can't imagine how you did without it.
