Bring the needle out with the thread at the top and hold down with left thumb. Insert the needle where it last emerged and bring the point out a short distance away. Pull the thread through, keeping the working thread under the needle point.
Chain stitch can be used an outline stitch or worked in close rows as a filling.

Fig 2 Bring the needle out at B and, keeping the thread under the needle point, pull the loop of thread to form a chain.
