In knitting, a gather draws stitches closer together within a row of knitting. Common methods include:

• In binding, a yarn loop is passed over 2 or more stitches in the same row (usually adjacent to the binding loop); also known as a pullover stitch.
• In clustering, the yarn is wound laterally around a set of stitches in the same row, possibly several times; also known as a wrap stitch.
• Smocking is a sewing or embroidery technique in which the tiny pleats are drawn together with thread or yarn. Before the development of elastic, smocking was used to provide a stretchable, flexible panel of fabric.

In the sewing technique ruching (pronounced /ˈruːʃɪŋ/, ROO-shing also spelled rouching), a large number of increases are introduced in one row, which are then removed by decreases a few rows later. This produces many small vertical ripples or "ruches" in the fabric, effectively little pleats. The technique of shirring produces a similar effect by gathering the fabric in two parallel rows (not necessarily horizontal), usually by smocking.
