Very beautiful and bright wall art in red, orange, bright and pale yellow colors. I used over 600 nails and silk & cotton strings (70% silk - 30% cotton, which makes them rather unbreakable). The board contains 2 sheets of black foam boards. They provide a great black background and not heavy. Total thickness is 3/4". All materials used are eco-friendly, while I never use spray paints or other toxic materials. The size of the board is 20'' x 20''. Can be hang diagonally or vertical. Totally customizable, you can change the size and colors. Also looks good with only 2 colors.
