Boring practical question... but for those of you who use reusable nappies, what do you use to line your bucket? I can't find any net bags the right size to line mine and I would really prefer one of those waterproof bags made of the same sort of material as the all in one nappies but haven't come across them anywhere. Amazon is no use as the net bags on there don't give measurements! My bucket has a 100cm circumference around the top so if you have a similar sized one I'd love to hear what you use to line it. So far I've sewed one cotton liner but it will probably fall apart after a few washes.
