A customer recently visited my shop, and asked if I could make some newborn diapers for her friend's baby shower. "Sure!" I said. Then the customer asked if I could make them so that they would fit for a long time, as newborns tend to outgrow everything they wear in the first 2 weeks. Hmmm excellent point..."Let me see what I can do"
So after fooling around with paper and pencil and ruler, I came up with a diaper that adjusts with snaps, to fit a tiny newborn hiney, as well as a chunky 18 pounder! The adjustable covers, were the next logical step! :o)
