Prefolds are the most economical choice in cloth diapering. They are also the most versatile. Prefolds are rectangular diapers with layers of absorbent materials divided into three sections. The two outer sections are less absorbent as the middle section. You will want a prefold diaper that says either 4-6-4 or 4-8-4. This means that the two outer sections have 4 layers while the center sections have 6 or 8 layers. You can choose from Indian and Chinese prefolds or our wonderful 100% organic Vermont Diaper Company French terry prefolds. Indian prefolds are softer but may not wear as long as the Chinese version. The Chinese prefolds may last a little longer but aren't as soft against baby. The 100% organic prefolds by the Vermont Diaper Company are soft, absorbent and very durable. All unbleached prefolds need to be washed and dried in the dryer a minimum of 8 - 10 times before use to strip the natural oils that cause repelling. A waterproof cover or wrap is required over prefolds to prevent leaks. Many covers are made so that you do not need to use pins. Most covers are made with snaps and Velcro for easy use and are manufactured from wool, fleece or a waterproof polyester laminate material.
