Hi, I made diapers from flannel. The diapers were shaped and cut with one short side on the selvedge edge. I made them in 2 sizes. When the baby had outgrown the smaller ones, I inserted them into the larger ones for more absorbency. My kids were allergic to the plastic used on the first disposable diapers that came out. Good luck with making them. By the way, my children are from ages 45 through 33 years old now. Good luck on making the diapers and finding a suitable fabric for them.
