E. g. there is a rule that no parallelograms may be put from the glazed tiles.
With these two rhomboid basic elements I started to play. At first I imitated the Penrose tiling to understand the rules and fill an area completely. I then broke the rules to create gaps consciously. I began to fold the basic elements out of the tiling and let them grow into space.
A variety of jewellery has resulted from these different models.
