Ah Ha! Latest Mycelium furniture design. Custom lettered coffee table bases. Just hemp pulp mixed with living mycelium. The mycelium grows through the hemp transforming the loose fibers into solid, strong structural forms. Once it is grown out I shock it with heat to kill the living material and prevent fruiting or spores. When your done with it just throw it into the compost. These letters are 12 x 12 x 17 each.
