The AMS hosts hands-on activities at the biennial USA Science & Engineering Festival. In 2018 Susan Wildstrom and some of her students from Walt Whitman High School in Bethesda, MD, led the line-drawing activity and in 2016 she and her team, with help from AMS staff, led the curve-stitching activity. Whether or not you attended the festival, here you can learn more about how to make line drawings and stitch curve patterns, and see the math behind the patterns.
Make beautiful geometric patterns from simple lines. The designs can be basic or complex, depending on the template you choose.
The designs can be basic or complex, depending on the template you choose. See the mathematics behind line drawing, including animations, in "Hearts and Roses," by David A. Meyer.
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.

A few weeks after the 2014 festival, AMS staffer Samantha Faria noticed this on her way to work.
