Pre-folds and flats are the most economical diaper system available! Fold them in thirds and lay them inside a diaper cover OR get creative with your diaper folds and secure with a Snappi or diaper pin. Traditional pre-folds are made with cotton but newer options are available in both hemp and bamboo. You’ll need a diaper cover or wool to keep wetness contained. These diapers are also wonderful for burp cloths, household clean-ups, and so much more. Flats are also very popular with parents on a budget or families who travel frequently. Flats take up very little space and can even be hand washed if laundry facilities are unavailable. Flats are usually only one single layer of fabric that can be folded to create more absorbency and dry quickly.
