Friends are expecting baby number two so they've decided that she will stay home with their children. To cut corners, they've been looking into cloth diapers and asked me to work up a price for the materials to make them. I've searched through so many different patterns online but I'm not finding a pattern that answers my main question: What do you put in them for absorption? And what do you use on the outside for leak control? I've seen these things handmade in the past but never had cause to inspect them. All the online patterns do is give me yardage for fabrics to be used, not a description of the fabrics.
