                  6. Construction Overview<\/strong><\/h2>\n\n\n\n

                  This jumper is knit top-down in one piece<\/strong>, starting at the neck and working down through the yoke. The sleeves are separated and held while the body is completed. Then the sleeves are knit down from the yoke using the live stitches\u2014no seaming required!<\/p>\n\n\n\n

                  This construction method is ideal for beginners and produces a clean, seamless garment.<\/p>\n\n\n\n

                  \n\n\n\n

                  7.1. Neckline & Yoke<\/strong><\/h3>\n\n\n\n

                  Cast-On and Ribbed Neckband:<\/strong><\/p>\n\n\n\n

                    \n
                  1. With smaller needles (4.5 mm), cast on 72 stitches<\/strong> using a stretchy cast-on method.<\/li>\n\n\n\n
                  2. Join to work in the round, being careful not to twist.<\/li>\n\n\n\n
                  3. Place a marker to indicate the beginning of the round.<\/li>\n\n\n\n
                  4. Work K2, P2 ribbing<\/strong> for 1.5 inches (4 cm)<\/strong>.<\/li>\n<\/ol>\n\n\n\n

                    Switch to larger needles (5 mm)<\/strong> and begin raglan increases<\/strong>:<\/p>\n\n\n\n

                    We will now define the raglan structure:<\/p>\n\n\n\n

                      \n
                    • Divide the stitches as follows:\n
                        \n
                      • Back: 20 sts<\/li>\n\n\n\n
                      • Sleeve: 10 sts<\/li>\n\n\n\n
                      • Front: 20 sts<\/li>\n\n\n\n
                      • Sleeve: 10 sts<\/li>\n\n\n\n
                      • Place markers between each section (4 markers total)<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n

                        Raglan Increase Pattern<\/strong> (every other round):<\/p>\n\n\n\n

                        \n

                        Increase 1 stitch on either side of each marker using M1L \/ M1R<\/strong> or KFB<\/strong>.<\/p>\n<\/blockquote>\n\n\n\n

                          \n
                        • Work raglan increases every other round<\/strong> until:\n
                            \n
                          • Back\/front sections have 44\u201346 stitches each<\/strong><\/li>\n\n\n\n
                          • Sleeves have 36\u201338 stitches each<\/strong><\/li>\n\n\n\n
                          • This will take about 18\u201322 rounds<\/strong> depending on your gauge and size.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n

                            Try it on over the child’s head (if possible) or measure to make sure the yoke depth is around 6.5\u20137 inches (16\u201318 cm)<\/strong> from neckline to underarm.<\/p>\n\n\n\n

                            2. Cast on 8\u201310 stitches<\/strong> under each arm (bridging the gap).<\/li>\n\n\n\n
                            3. Join back and front sections together and continue knitting the body in the round<\/strong>.<\/li>\n<\/ol>\n\n\n\n
                              \n\n\n\n

                              1. Continue in stockinette stitch (knit all rounds)<\/strong> until the body measures 13\u201314 inches (33\u201336 cm)<\/strong> from underarm or until desired length.<\/li>\n\n\n\n
                              2. Switch to smaller needles.<\/li>\n\n\n\n

                                  • Knit until the sleeve measures about 14 inches (35 cm)<\/strong> from underarm or desired length.<\/li>\n\n\n\n
                                  • You may choose to decrease 1 stitch every 6\u20138 rounds<\/strong> to taper the sleeve slightly.<\/li>\n<\/ul>\n\n\n\n

                                      • If using wool, use a steam block or wet block. For acrylic, a gentle steam with a pressing cloth works best.<\/li>\n<\/ul>\n\n\n\n
