You know that fold of fabric created when you snap down the front of a one size cloth nappy to adjust its size? Have you ever wondered whether there's a 'right' direction to fold it?
Love this little video from GroVia demonstrating that folding it up is generally better than down - it creates less bulk and a better fit across the thighs. And yes, this is the case for most nappies with an adjustable rise.
