This cowl is a nicely textured fabric, done in the round using knit and slip stitches.
Pattern can be widened or lengthened.
Gauge is not a huge factor in this project
2 skeins total were used in the pattern one each of contrasting colors, in this sample,
uses: US #6-40” circular

Please note, each round begins and ends differently, do not get caught up in the slip4, knit 4 trap.
