How to crochet a chain stitch (ch)
The chain stitch (ch) is often used to increase the height of a new row, to create embellishments like hair for a doll, or to add a hole to a piece like to make a basket handle. If a chain stitch is the first stitch in a pattern,that’s your cue to make a “foundation chain”. The only difference between a foundation chain and a regular chain stitch is that it starts with a slip knot.
To make a chain stitch in crochet, yarn over. Pull the yarn through the loop on the hook. There should be one loop left on the hook.
Minimize the chance of twisting your chain by constantly moving your left hand to hold the chain as close as possible to the hook.
