Knitting and crochet are two related textile crafts that transform yarn into fabric, yet they differ in fundamental ways. Knitting uses two or more needles and holds an entire row of active stitches at once, while crochet uses a single hook and works with only one active stitch at a time. Both crafts build fabric from loops of yarn, and a single loop is called a stitch, the basic unit of all knitted and crocheted cloth.
The simplest knitted stitch is the knit stitch, made by drawing yarn through a loop from front to back. Its mirror image is the purl stitch, drawn back to front. Because these two stitches can be combined in different sequences, an enormous range of textures and patterns emerges from just this small vocabulary. Crochet similarly builds from a few foundational stitches that vary mainly in height, allowing the craft to grow fabric quickly in three dimensions as well as two.
Both crafts share a rhythmic, repetitive quality that many practitioners find meditative. The hands move in predictable cycles, the eye learns to read the growing fabric, and a project slowly accumulates row by row or stitch by stitch. This combination of motion and visible progress is part of why knitting and crochet have endured for centuries and continue to attract new makers today.
