Curve Stitching

Curve stitching, or string art, is a beautiful way of combining geometry with art. These wonderful designs are created on different shaped grids, and straight lines are sewn or drawn to look like curves.

Mary Boole designed string geometry to help children learn about the geometry of angles and spaces.
