I used two skeins of Lion Brand Gold Leaf in Teal Gold with size 15 circular needles.
Co 70, join without turning
Row 1: (yo, k2tog) to end
Rep row one until your cowl is as wide as you would like.
Bo loosely in k.
Fasten off, and weave in all ends.
This stitch creates a nice lacy rib type texture. I love the gold peaking through on the occasional stitch!
My finished cowl is about 10"x38".
