I wanted to use up my worsted weight acrylic yarn, so I decided to knit a wavy blanket and change colors every few rows. I never know for sure how far my skeins of yarn will take me. This turned out as a nice size baby blanket. The pattern is a free pattern called the Feather and Fan Throw on Ravelry. It's an easy pattern to knit too.
Used up yarns of purple, pink, white, blue and a variegated yarn of purple, pink and white.
