These painted boards, approximately 15cm x 15cm, will be delivered with nails already hammered in. The paint is applied to the surface and sides only. The first photo is a sample of the finished product, so the size is different. Please refer to the second photo for the actual product. *This is a sale of the board only; the thread is not included. There are no instructions on how to string the thread, but I will provide the numbers for where to place the thread. You can search for "Ito Kake Houou" (Thread Art Phoenix) on YouTube to see how to string the thread.
