Draw Varying Line Thickness

There are two ways to achieve line thickness variation:

1. Draw two shapes, one on top of the other. Both shapes are set to zero line thickness. The shape behind is then set to the desired line color. By adjusting the points for the shape underneath and making it slightly larger than the shape on top, you achieve the look of a line bounding the shape on top.

2. To achieve a line that looks a little more hand-drawn, use just one shape with the line thickness set to 1. Go along the line and plunk down a few random additional points and intervening curves. Then move these points and curves just slightly out of line, in a random, pencil-like way, until the line looks more hand-drawn. Still relatively straight and all, but with slight variations in placement and thickness so it looks a little more natural.
