The pattern is written in U.S. crochet terms, complete with clear instructions and pictures to help you along the way. Charlie The Chick is crocheted in continuous spirals without joining the rounds. I suggest using a stitch marker or different color yarn to keep track of each round. Charlie The Chick is crocheted in worsted weight yarn and is approximately 4 inches tall. Be aware that the final size may vary depending on the yarn and hook size used. Gauge is not particularly important, just be consistent with the tension you are using. And, most importantly, have fun!
