London-based designer Julia Lohmann used an unconventional material to create this lampshade: seaweed She thinks that dried strips of seaweed could replace leather, paper and plastic to make everyday objects like these laser-cut kelp lampshades. Lohmann used a laser cutting machine to create patterns in pieces of kelp before sewing them together, or stretched them into shape while wet to dry into new forms. The malleable strips are also wrapped around rattan structures to create a variety of shapes. The rattan acts like a skeleton and the seaweed is like a skin on top of it.
