To remove glass, gently open tabs on left, top and bottom of each side of lantern. Carefully slide out glass, and set aside.
Paint lantern desired color, and let dry.
Once dry, turn glass over so design faces down. Paint back of glass desired color with a sponge brush, blotting the paint to avoid visible brush strokes.
Use gold leafing pen to color decorative trim.
Carefully place glass back in lantern, alternating colors and patterns as desired.
