Make several of these quick-knits for gift giving. Only 1 skein of yarn (3.5oz.) of number 4 medium yarn is needed. This design uses the same instructions for Toddler to Teen sizes, only the needles are different. It is knitted in one piece from sleeve edge to sleeve edge, seamed on the sides. This makes for a very "stretchy" garment. Lots of wear possibilities. Two sizes: the toddler size fits 21"-24" chest measurements and the teen size fits chest measurements 26"-28".
