It is a top-down, asymmetrical, rounded triangle shawl increasing at both ends alternately. The center stitches aren’t straight down the spine but instead at an angle. The fan side of the shawl will be longer than the shell side. Any yarn and colours will be great for it.
Gauge is not important.

Measurements: Top edge 67” x 20” deep
