When my first grandbaby was born almost 3 years ago, my daughter wanted to use cloth diapers. Here is a pattern I used/adapted. I tried the sewn in liner, but they took too long tp dry so made "pocket" diapers instead.

I searched online and there is lots of info and free patterns. I practised first using cotton flannel blankets and towels from the thrift store. Then JoAnns had a 70%(!) off sale on suedecloth, so I bought several yards to use for the lining, and cute flannel prints for the outside. Then I made diaper covers(we used to call them rubber pants!) that are made of waterproof fabric called PUL that close with velcro.
Here are two more sites with lots of info.

I used cloth diapers when my adult chuldren were babies, was so glad my daughter chose the same. But I never had such fun, cute cloth diapers as they have now.
