Curve Stitching -- How-to and Learn more
Curve stitching 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.
Curve stitching was invented by Mary Everest Boole in the mid 1800s.
The AMS hosted this activity at the 2014 USA Science & Engineering Festival held in Washington DC April 25-27. Susan Wildstrom and some of her students from Walt Whitman High School in Bethesda, MD, led the activity, helped by AMS staff Anita Benjamin, Mike Breen and Colleen Rose. Whether or not you attend/attended the festival, here you can learn more about how to stitch curve patterns and the math behind the patterns.
Download and print pattern sheets (1, 2, 3, 4) with instructions. All you need is some yarn and a safe plastic needle.

Math on the street
A few weeks after the festival, AMS staffer Samantha Faria noticed this on her way to work.
