Beth from 110 Creations shares a tutorial at Sew, Mama, Sew! showing how to make her Reversible Cozy Hood for Kids. It fits around the head and over the top of the shoulders and neck to keep your child warm when out in the cold weather. Her tutorial shows how to draft a pattern using a hood (or hoodie) and a t-shirt that fit your child, and then how to sew the pieces together to make the hood. Go to Sew, Mama, Sew! to find her tutorial.
