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.
