For the second formfinding method, we utilized a frame-based system where the sides of the frame are marked with holes on a grid. Two overlapping layers of fabric were used, the fabric was stretched by pulling string through the holes. Different methods of stretching were utilized, such as overlapping the nodes, stretching one layer into the other and tying the edges. The fabric was then painted with thin layers of plaster, glue and water consecutively. The strings were cut when the shell has hardened and the HYBIOS was sanded and cropped around the edges .
