In-Person Talk 

Hitomezashi patterns, which originate from traditional Japanese embroidery, are intricate arrangements of unit-length line segments called stitches. The stitches connect to form hitomezashi strands and hitomezashi loops, which divide the plane into regions. This talk will discuss the delicate techniques that Noah Kravitz and I developed to understand hitomezashi patterns, along with the deceptively simple-looking results that we proved using these techniques.
