What style of cloth diapers will you make? You can read up about prefolds, fitted, pockets, and all-in-one (AIO) diapers here if you need a diaper style crash course. Prefolds require only very basic sewing skills, but even a beginner can sew fitted, pockets, or AIOs. All of the patterns listed below are available free online. Very Baby also sells high-quality patterns on its site for around $10 each.
Prefold patterns - To sew prefold diapers, follow this free tutorial from Very Baby. This pattern illustrates how genuine prefold diapers are made and how to recreate them at home.
To sew prefolds from recycled materials, such as old T-shirts, follow this pattern from Fern and Faerie.
Fitted diaper patterns - To sew fitted diapers, you will need elastic for the legs and back of the diaper in addition to your diaper fabric. You may also want to attach some form of closure, such as Aplix or snaps, to the front.
