Yes, the pattern called for one colour for the body and a different (VERY contrasting in the book) colour for the ribbing around the body and the sleeve cuffs. It was too flashy for my liking so I made it one-tone instead of two!

, and scroll down to 'customer images' you can see what the shrug in the book looks like. It's the hot pink one with blue ribbing.
