My daughter has cloth diapered both of my grandsons. I found free patterns on line. I was shocked at the prices of new cloth diapers. It is very common to sell used cloth diapers. If you do a google search for cloth diapers you'll get tons of good information. Be sure to use poly thread because cotton thread will wick moisture. I was making so many of them I invested in a really good snap press.
If you have an embroidery sewing machine you can get real fancy with designs. These are certainly are not the cloth diapers of years ago.
Neither of my grandsons have had skin rashes or problems. My daughter always hung her diapers out on a clothes line.
