1. Paint the bottom bases of wine glasses in desired colors. Allow the glasses to dry upside down. Apply additional coats of paint as necessary until the painted areas are opaque.
2. Once dry, flip glasses right side up. Add small dots of paint to the top of the base, neck and bottom portion of glass using various colors. Make the dots closer together at the base and spread them out whiling moving up the glass.
3. Allow the painted dots to dry thoroughly. Apply an additional coat of paint to any dots that do not appear opaque.
