Drawing a 3D cable

[Psaumure]

Hi JimR,

I know there are a lot of ways to do this but this is a simple method.
Draw a line along the curve of the wire about four pixels with. Set it at the darker shade color and then clone it. Change the top color to the lighter white. Feather the bottom color slightly and then feather the top color will more aggressively. Move the top color back to little to give your three-dimensional role. Group the two colors and apply a little shadow.

I attached a picture of how it would look completed. Hope this helps.
