This baby blanket was crocheted using a washable worsted weight acrylic. It is crocheted as one whole piece. There are no seams, even though it looks like it has squares. The pattern was given to me by one of my knitters' guild members. It's called Spiderweb - a "Leisure Art's Pattern".
It is easy to crochet and works up fairly quickly. Using a size G (4.5 mm) hook and approx 370 grams of yarn, the finished size is approx 35 x 47 inches.
