This sweet little newborn hoodie sweater is only available in the newborn size…more sizes will be added in the future. I used a circular needle in U.S. size 6 as well as DPNs in U.S. size 6. I knitted mine in Hobby Lobby’s Baby Bee Sweet delights….it took 1 skein. However, any #3 yarn will work for this pattern…..You could use a #4 yarn but it will result in a tighter stitch and a bit larger overall size of the sweater.
