Thirty years ago - gulp - I repurposed COTTON flannel sheets and receiving blankets in rectangular pads. The pads were three layers thick and the seams were enclosed. I am infamous for making things that last....so....I topstitched around the perimeter and then stitched diagonally corner to corner....once each vertically and horizontally.
The original idea was to start out using these as burp pads. When the children were much larger the extra pad was placed between two regular cloth diapers for overnight duty. We had twins and I could not afford the use disposable diapers on a daily basis.
Another mother of twins taught me how to do this. By using the nicest receiving blankets I purchased at garage sales for the outside covering, the pads were inexpensive, attractive, comfortable, and very useful:) I did not feel poor. Thank you Chris B.!!!!
