I, Danyle, started making my fleece diapers about in 2010. My boys, Chuck, Pudge, and Peanut, that I had at the time were Frizzle Bantams. Chuck and Peanut didn't have many feathers for the first 3 years of his life so I needed something to catch the poo and be soft on Peanut's skin. I hate to hand wash things all the time so I made the diapers sturdy and simple enough to go through the washing machine and the dryer. The sewn in insert/lining is made from the same material as Washable baby diaper water resistant pull ups. The buttons are plastic and the fleece is a soft, fluffy polyester blend.
