What is a prefold upgrade?  It is a rectangular piece of micro fleece, finished with binding on the edges.  It snaps around a prefold diaper--there are two snap settings which accommodate smaller and larger prefolds.  AbbyCadabras original prefold upgrades work like this:

Prefold Upgrades are excellent because they

    * Snap in place, to prevent  bunching

    * Wick moisture away from baby's skin

    * Feel very soft and dry, even when wet

    * Are stain resistant--protecting prefolds from stains

    * Are easy to remove stools from   

    * Are excellent for night time

    * Dry quickly after washing
