Like the Herringbone parallelogram Scarf the Herrinbone Rectangular Scarf is written for fingering (sport, dk, worsted) weight yarns as if they were sizes. And it is worked flat on the bias.

Unlike the Herrinbone Parallelogram Scarf this scarf has squared off ends. It starts and ends with a triangle wth a parallelogram in the middle. Since the Rib and Welt Diagonals pattern naturally distorts the fabric, there is a strange increase/decrease ratio in the triangles. It was important to me that the increases flow through the rest of the fabric neatly, so there is almost a different increase method used on every row.
