This lovely cowl can be worked in fingering to light sportweight yarn (shown in glorious Bijou Basin) or laceweight yarn.

The main pattern is a modified Print O’ the Wave. To me it looks like kelp fronds.

Notions & supplies: Beads Size 6/0 (laceweight version only): 112 if knit as shown. 16 total beads for edging, 96 beads for center.
Yarn needle
Crochet hook for beading (or) dental floss.
