Fleece liners protect your diapers from rash creams plus they make cleaning up messes a breeze. Also, when used with a cotton or hemp diaper, the fleece will keep your baby dry so she doesn't feel the wetness. To use the fleece liner, simply lay it on top of any diaper. It may be used with a prefold, pocket diaper, AIO, or fitted.  Washing instructions: wash once before use. Liners may be washed and dried with your diapers. Cold rinse, hot wash with 1/2 recommended detergent, then dry. Liners are 14"x5". Liners are sold individually.
