Hammering flowers to transfer their pigment onto paper is called Hammered Flower Art. This technique, also known as the Japanese art of Tatakizome, uses the force of a hammer to release the natural dyes from fresh flowers and foliage onto paper, fabric, or canvas. Process: The basic process involves placing fresh flowers or leaves on a surface like paper or fabric and then hammering them to flatten the petals and release their natural colors. Results: The result is a unique, vibrant print that captures the natural colors and shapes of the plants, creating botanical artwork. The artwork is then signed by the artist and framed.
