Raised lines travel across this cowl like streams of data moving through a network, with puff stitches as signals along the way. A graphic, modern texture from one approachable stitch repeat.

The cowl is crocheted flat in front post double crochet and single crochet, then seamed into a loop. It takes one skein of Big Twist Value in Medium Gray, a worsted weight acrylic that’s easy to find and easy on the budget.

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. Data Flow turns a network diagram into texture.
