Both pieces feature a stylized flower motif worked in stranded knitting technique. The mittens have a corrugated ribbing at the cuff, and a gusset thumb. I used Malabrigo's Arroyo, a lovely soft merino sportweight, in Black and English Rose. (This design definitely benefits from a high contrast between the two yarn colors.)
You can get a pair of mittens and the cowl (or 2 pairs of mittens or 2 cowls) out of one skein of each color, so it's a great gift project for the holidays too!
