Pick Up Stitches
Picking up stitches means knitting new stitches into the edge of existing fabric, such as at a neckline, button band, or after a heel flap.
Explanation
Picking up stitches is used to start a new section directly from the edge of an already knitted piece, without having to sew it on afterward. You insert the needle through the edge of the fabric, pull a new loop through, and repeat along the whole edge, typically at a neckline, along a cardigan edge to knit a button band, or along the sides of a heel flap to continue down toward the foot. It's common to pick up slightly fewer stitches than the number of rows to avoid the edge rippling.
