When making a pullover sweater in either knitting or crochet, there are many different ways to construct a sweater. In some cases, you will be working from the top-down in one piece (working from the neckline downwards, adding stitches for your raglan sleeves, and then coming back in for the body); you might also work in the round from the bottom edge, splitting the stitches at the arm holes and then working on the front and back separately.
Often you'll see instructions like this:
- K14 (15, 16, 16) sts, join a 2nd ball of yarn and bind off next 6 (8, 8, 10) sts, k to end. Working both sides at once with separate balls of yarn, dec 1 st at each neck edge every other row 3 times - 11 (12, 13, 13) sts. Work until same length as Back to shoulders.
When you shape the neck of the front of a pullover, in particular a crew neck or a v-neck, you are ensuring that the neck opening will be large enough so that it fits over the head. There are two components: the width and the depth.
The depth is generally several inches. This is why the neckline shaping begins before the front armhole reaches the depth of the back armhole (where usually only width is of consequence to the total neck opening).
To begin, stitches are eliminated in the center and then decreasing takes place on each side of these center stitches to further widen and shape the neck opening. When the depth is completed, the shoulder stitches are usually bound off.
We'll be discussing how to shape a neckline when you work the sweater in pieces, starting from the bottom edge and working up towards the neckline.
