For the first few practice tangles, use a pencil to draw a circle - or use a penny to trace one. This is easy to do freehand but for your practice it helps to know where you are going.
Start with an easy 'S'.
Bring a curved line down from the end of the 's'. Stop in the bottom of the circle.
Repeat, going upward from the other end of the 's'. Stop at the top of the circle.
Add a small circle at the top and bottom.
As you are working this you will discover that you can go ahead and do the small circles as you do the side curved lines. At this point there will only be 3 steps to do this tangle.
