First, paint the bottom of a glass ball ornament with two coats of white acrylic paint; let dry after each coat. Then use a small, round brush to paint white trees in different sizes. Once the trees have dried, add small dashes of red acrylic paint to the trees to resemble cardinals. After the red paint has dried, use the bristle tips to add small white dots for falling snow.
