I have spent a lot of time recently getting all the loose ends up with sewing. I had a bunch of extra knitted fabric in my closet that I had no real use for, so I decided to make something called tie nappies. This pattern has been around for at least 100 years. It is a one-size fits all kind of diaper that you can tie on. They are especially great when used at nighttime because you can put them over another fitted or prefold. I made a few with the fabric that I had available. I LOVE them.
They just look like square blobs in the photos, but you can at least get the idea of the fabrics and the ties.
