Note from the designer:

This project will teach you to make a soft and snuggly baby blanket. There are two options available, so this pattern can result in different blankets for different babies. While the blankets are basically the same, the second variation will be more delicate, with smaller blocks.

Option two: Needle size 7 circular. DK weight yarn, 955 yds. 5.5 sts= 1 inch.
