Pushing the Envelope 12" x 18" Poster 

This poster features curve-stitching and its relationship to mathematuics. Curve stitching, invented by Mary Everest Boole in the mid-1800s, is similar to string art in that the way yarn or thread is pulled through hole patterns forms wonderful geometric patterns. The designs can be simple or complex, depending on the placement of the holes and the sequence of where the yarn is pulled.
