Uhmmm, I don’t really DO tutorials, but I am tired of people not knowing about the smooth tool in flash!!  Even if you use a mouse to draw lineart in flash, you can use the smooth tool to make it look perfect.  I used my tracpad to squiggle a couple lines on top of an old sketch.  This tool saved my life on several projects.

Sorry if it’s a little hard to understand, but the important part is knowing where the smooth tool is in the menu, and hotkeying it!  I hotkey smooth to ` personally.
