If you have extra clay pieces store them in a resealable bag.
If the clay pieces begin to dry out, place them in a resealable bag and spray them with some water. Seal the bag and wait a few hours. The clay should be ready to use.
If you have larger pieces that have completely dried, or old unpainted projects you want to reuse, you can still revive the clay.
Break the dried clay into smaller pieces. Soak the pieces in a container overnight. Drain the excess water and work the clay into a ball. It should be ready to use.
