Make a Chain Stitch

The chain stitch is used to create a foundation for most crochet work as well as to create space between other stitches in openwork or lace patterns.
Its pattern abbreviation is CH or ch.

Chain stitch steps:

1)- Start with a slip knot on the hook.
2)- Yarn over. To do a yarn over, wrap the yarn over your hook from back to front so that
the yarn is coming toward you.
3)- Draw the yarn through the first loop on your hook (the slip knot). You’ve made 1 chain stitch. There is also 1 loop left on the hook.
4)- Yarn over. Draw the yarn through the loop created by the last chain stitch made.
5)- Repeat step 4 until you have made the desired number of chain stitches. (Do not count the slip knot as a chain. Also, do not count the loop on the hook.)

Note
Adjust your hold on the chain as it grows so that you’re always holding it
near the hook.
Keep the chain hanging down from the hook. Do not let the stitches you’ve
made twist around on the hook.
