We bought a new fabric which was far more stretchy than any of the previous materials. We used the same square cut pattern as before. Although they ‘popped’ out less, the material was far more suitable for the experiments.
We finally decided to create a large rhombus from several other rhombi with the new material. We had a ‘gradient’ of number of cuts in the rhombi going from 2 cuts to 36 cuts (6×6) This was quite successful, so we are going to continue experimenting with the 4×4, 5×5, and 6×6.
