Sound waves and signal patterns become a graphic filet panel on this structured tote, framed by dense Alpine stitch texture. A firm base and sturdy body make it an everyday bag with a STEM story.

The tote is crocheted in rounds, starting from a firm base and working up the body. Purchased handles are sewn on at the end. It’s worked in Cascade Ultra Pima, a DK weight Pima cotton that gives crisp stitch definition and holds its shape.

This design is part of the STEM issue of Knotions, our celebration of wearable STEM: knits and crochet inspired by science, technology, engineering, and math. Waves of Sound puts a sound wave on your shoulder.
