I am using the Sweater Workshop Book and made the sweatshirt with hood sweater. It states if I do not want a pointed hood to decrease every other outside round in the middle of back (k2tog, k1 ssk) after 5" going to 10" tall. I started the decreases at 7" and finished the hood at 14 1/2. It is pointed. i DO NOT WANT A POINTED HOOD. How do I shape it to make it rounded? Thank you in advance for your help.
