Make a loop, hook another loop through it.

Tighten gently and slide the knot up to the hook.

yoh, (which is actually winding the hook under the yarn from the front.)

Draw the yarn through to form a new loop.

Keep moving your left hand close to the hook every two of stitches or so.  This keeps the work easy to control.

<<<<<< Front

Back >>>>>>

To count the chains correctly, do not count the loop on the hook.
To count afterwards, make sure the chain is not twisted and you are looking at the front.
Ignore the loop still on the hook.
