The trees are trained along pre-defined routes following a blue plastic mold. The growing tip is shaped and held in place with small plastic clasps. The trees are gently manipulated to create the exact shape of chairs, tables, mirror frames or lamps. You can’t force the trees as a tortured branch dies back and will reshoot elsewhere. The shaping can be inch-by-inch over the span of a few years. One tree has been planted specifically to grow each piece. Some of the pieces use grafting as part of the design. This process of growing the piece take somewhere between 4–8 years. During this time a piece thickens and matures before being harvesting in the winter. Once seasoned the pieces are cleaned back and finished off to show the wood grain.
