Easy to knit from the top down! So easy, you can knit up lots of these! Fits from 6 months to almost 3 years. Uses worsted weight yarns, and knitting needles, US #5 and # 7. We put a very easy pattern of a fish and “seaweed” on the front of the cardigan. Pattern tells you how! You can leave it off, if desired, but we think it makes it look very cute! You can use the “fish” pattern to sew on other children’s clothing too!
