Thank you for viewing. By hammering 18 nails into a 30cm square piece of burnt paulownia wood and stringing thread in a consistent rhythm, geometric patterns emerge. "Black," which signifies protection, and "White," which purifies the mind and body. The beauty created by the threads will help create a healing space. The finish is quiet, elegant, and calming. I hope you feel the power of healing. This is a handmade piece. We appreciate your understanding regarding any nail distortions or imperfections when purchasing. Thank you very much. (^-^)
