An easy way to crochet a baby blanket is to use a simple pattern with either a large stitch, such as the double crochet stitch, or a bulky yarn. A bulky yarn requires a large crochet hook and is easy to manipulate.
Baby blankets are usually between 25 and 35 inches long, and can have square, rectangle or spiral shapes. A simple pattern repeats a single stitch or a simple specialty stitch, such as a scallop stitch. Any special stitches have instructions at the beginning of the pattern. Some patterns create a thick blanket by stitching two or three strands of yarn together with a large crochet hook. Patterns typically call for several skeins of yarn. Stripes of different yarns can make a simple pattern look fancier, and changing to a different yarn at the beginning of a row is easier than changing yarn partway through a row.
Free patterns for easy baby blankets are available on blogs, yarn company websites and pattern websites such as Ravelry.com. Some yarn company websites, such as LionBrand.com and RedHeart.com, provide baby afghan patterns and sell bulky baby yarn, such as Red Heart Baby Clouds and Lion Brand Baby's First Yarn. Some yarn companies require creating a free account to access the patterns.
