Working from top to bottom, bring the needle up at 1 and create a loop
by reinserting at 1; do not pull the thread taut. Bring the needle back
up at 2, keeping the needle above the loop and pulling the needle toward
you gently to tighten the loop so that it is flush with the fabric.
Tack the loop down by inserting the needle at 3. Repeat for the desired
number of stitches.
