Mix Spirography with String and Cardboard

The Spirograph is a mathematical toy, which enables the user to draw complicated patterns. In its most basic form it consists of a fixed circle, used as a template, and a smaller rolling circle with holes. But it is the repetitive lines of the Spirograph that interests us. Trace the recurring lines of the Spirograph with multicolored wools or yarns along evenly spaced cuts on a recycled cardboard circle. Repeat the pattern several times. Change color. Add a new pattern. Again and again until your contemporary geometrical double sided star ornament becomes a significant piece of string art.
