The pattern is written in U.S. crochet terms, complete with clear instructions and pictures to help you along the way. Bunny Ear Teether 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. Bunny Ear Teether is crocheted in organic cotton DK yarn and the ears are approximately 2 inches tall on the wooden teether. 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.
