Shawl worked in one piece in two-color brioche stitch, two rows are worked for each counted row that appears on the face of the fabric.
You should use either circular or double pointed needles when working two-color brioche so that you can slide your stitches back to the other end of the need to pick up the color you need to use.
Gauge is not critical for this project but will affect the final project dimensions and yardage required.
Yarn requirements: any Sport or Fingering yarn (as wool) or any other shawl yarn of your choice. I used 350 meters (380 yards) for each color of 100% Merino wool yarn 300m/100g.
