I am a kiwi artist living up on the Kaipara Harbour. Now also in to the copper wall hanging art. It is a heavy gauge copper.. I then put a blend on the copper which oxidizes it...... giving it the turquoise finish. Each piece I do is slightly different from the other. With the size, shape or colour. This is a whale tail hanger shape...with a tie hanger made with nz flax. The dimensions are 14cm x 20cm at widest.
