I used the dark color for the ribbing for both hats.

Yarns listed above are for the darker hat (foreground in first photo, and third photo). I knit with the dark color in my left hand and light color in my right for the darker hat.

The second, slightly lighter hat, uses Sweet Georgia Superwash Worsted, color Evening, and Blue Sky Fibers Woolstok Worsted, color Spring Ice. This hat was knit with the dark color in my right hand, which I like better.

After the chart, I knit six extra rounds before decreasing for both hats.
