Thank you for viewing. By hammering 24 nails into a 20cm square piece of burnt paulownia wood and weaving thread around them in a consistent rhythm, a lace-like pattern emerges. "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 and calm. This is a handmade piece. Please understand that there may be slight imperfections such as nail distortions or unevenness before purchasing. Thank you very much. (^-^)
