Symmetry in Pacific Northwest Baskets
Native designs and cartesian coordinates
Since most native baskets are made up of rows and columns of roots or other materials, they make up a grid, like a Cartesian coordinate system. A Cartesian graph can be used to visualize basket decorative designs very well. It is also very easy to observe how symmetry works in the basket designs when we use a Cartesian graph to analyze them. Furthermore, we can use a Cartesian graph to create our own symmetrical patterns, whether they demonstrate reflection symmetry across one axis, across two axes, or rotational symmetry. Using the Basket Weaver software, you can apply a Cartesian graph to create patterns commonly seen in native basket designs, or create your own original designs.
