  • 1. Wax serrated knife with candle stub or paraffin. Refer to
    diagram to cut foam sheet into appropriate pieces. Smooth cut
    edges with fingertips.
  • 2. Mix 1-1/3 c. stucco medium with small amount red iron oxide
    paint in small bowl; add a drop or two each of yellow and
    white paints to create light coral color and mix well. Remove
    a bit less than half of light coral mixture to second bowl;
    add more white paint to create pale coral color and mix well.
    Cover bowls with damp paper towels.
  • 3. In third bowl, add a drop or two of black paint to small
    amount white stucco medium to create gray color. Cover bowl
    with damp paper towel. Note: Paint colors can change as they
    dry; test colors on scrap foam.
  • 4. Using firm paintbrush and diagram as guide, spread thin,
    even coat of stucco onto appropriate foam piece, covering top
    and sides only. Create one rectangle at a time to prevent
    uneven drying.
  • 5. Use putty knife to smooth surface of stucco. Dip soft
    paintbrush in clean water to lightly smooth foam edges where
    excess stucco tends to accumulate.
  • 6. Repeat Steps 4 and 5 to cover rectangles with appropriate
    colors; let dry completely. When dry, sand any imperfections.
    If needed, apply second light coat of stucco; let dry.
  • 7. Mix 1/2 c. spackle with 1 T. water in small bowl to create
    easy-to-spread mixture. Apply mixture to long, thin strips of
    foam, creating as smooth a surface as possible. When foam
    strips are dry, refer to painting diagram and spray paint one
    rectangle gold and remaining with two to three coats of
    platinum; let dry.
  • 8. Cut 24" balsa strips to 20" long using coping saw with fine
    blade; sand cut end smooth. Spray paint 20" strips and 1/16" x
    1/4" x 36" strip copper and remaining strips platinum; let dry.
  • 9. Use craft snips to cut these lengths from long copper wood
    strip: 12"; 7-3/4"; 6-1/2"; 5-1/2"; 4-3/4"; 4"; 3-3/4";
    3-1/8"; 1-3/8".
  • 10. To create design grid framework, arrange two 20" wood
    strips vertically on work surface, parallel to each other and
    16" apart. Center and glue three 36" strips horizontally
    across copper strips at 4" from top, center, and 4" from bottom.
  • 11. Refer to diagram to glue darker coral squares and
    rectangles to grid, followed by light coral and grey squares
    and rectangles. Glue metallic foam strips to tops of light
    coral and grey pieces.
  • 12. Refer to diagram to glue wood strips in place; most narrow
    strips will be glued onto backs of rectangles with exception
    of two strips glued to surface of top coral pieces.
  • 13. Cut two 3" lengths from wire; twist ends together to form
    hangers. Glue loops to vertical wood strips at top back of
    wall sculpture. Let dry completely before hanging.
