Making a dirty nappy bag?

[OnlyWantsOne]

For washable nappies
Id like to make a bag that can be washed often - that can house dirty nappies when out and about. Obviously it will have to have a water proof lining?

What to you think is best, drawstring?

Something like a terry towel bag removable inside an oilcloth one?

Must be able to buy water proof / resistant nylon type stuff? Then the bag could have a pretty outside and a practical inside?

I'd have to Pre wash them together wouldn't I?

TBH I find a plastic carrier bag is ideal, provided you can tie the handles together. Can be used lots of times too. However, a nice drawstring bag to put everything in (clean nappies, wipes, said carrier bag etc) would be lovely - I currently just have a dull freebie one.
