What to do With Leftover Paint?

Most artists don’t work with large amounts of acrylic paints only because they dry so quickly. If you wish to work with larger amounts you can purchase a palette that retains moisture. This plastic container with a lid for a snug fit allows the artist to place a wet sponge in the middle of the container. Your paints are placed in this container and as the water in your paint starts to dry up the paint will begin soaking up the water in the sponge to keep your paints from drying up.
