Need to vary the stroke on a path

Hi
If i draw a path and then stroke, is there any way to vary the thickness on some parts of this path? Thanks!

In the path's palette, there's a button on the top right with an arrow in it. Click on it and select Stroke Path... from the menu that pops up. In the new window, select Paintbrush and check the Simulate Pressure or something along that line. PRess okay. The result is that the ends of the path starts off thin, gradually gets thicker up to the center of the path and then gradually becomes smaller.

Thanx! But it seems like the precision is not there?

mess around with the settings til you get the desired effect. different paths require different settings!
try changing the brush also if you choose brush on the stroke path popup
