t-ch
Crochetturning chain
Description
A t-ch (turning chain) is a sequence of chain stitches worked at the beginning of a row to reach the height required for the following stitches.
Detailed explanation
In crochet, a turning chain is used to raise the yarn to the correct height before starting a new row, which prevents the edges from pulling or puckering. The specific number of chains depends on the height of the stitch being worked; for instance, single crochet typically uses one chain, while double crochet uses three. Patterns usually specify whether the t-ch counts as a stitch or serves only to provide height.
