Use these light-weight 3D Balls to achieve a special three-dimensional finish in the colour of your choice. Place as many 3D Balls as you will be using in a plastic cup, then add enough PENTART acrylic paint to ensure each of the balls is completely covered. Ensure, the surface you will be decorating is positioned horizontally, then use a small spoon or a spatula dipped in water to apply the spheres. Using spheres of different sizes and colours on top of one another produces an exciting effect! You can also mix them with Gel Medium.
