Let the yarn do all the work for you. These adorable boys' sweaters use Hayfield's self-patterning Baby Blossom Chunky to knit these cute sweaters. Sizes range from 0-6 months up to 6-7 years and the patterns use 1-4 balls of yarn, depending on the size chosen. Choose between a v-neck cardigan or a shawl-collar cardigan. Instructions for each are included in the pattern. This pattern calls for US9 and US10.5 needles.
