This pattern is a one-size fits most flannel fitted pocket pattern that does not have closures. It fits tiny babies to large toddlers and is very trim. It is a very simple fast diaper to sew up and you can find everything you need to make one at your local Walmart or fabric store. Did I mention that RRPs are also reversible? Use cute prints as the outer and the inner, and you have two cute looks with one diaper.
Here you can see how folding down the front of the RRP makes the rise shorter for smaller babies. The fleece covers pictured on here are made from the Mile High Monkeys pattern which I can't find any more. But I did find a similar one here.
For great FREE diapers and pull-on trainer pattern (which you can make with fleece and it becomes an excellent cover) please visit The Nappy Network. You can literally make a great cover for a buck or less.
