The pattern is written in U.S. crochet terms, complete with clear instructions and pictures to help you along the way. Olive The Owl is crocheted in the round/continuous spirals without joining the rounds. I suggest using a stitch marker or different color yarn to keep track of each round. Olive The Owl is crocheted in worsted weight yarn and is approximately 2.5 inches tall. Be aware that 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!
