1.
A form of shading in ink or pencil drawing\sketches, where one creates shadow or the suggestion of colour by drawing lines diagonally in one direction, and then cross-hatching them with similar diagonal lines passing in the other direction.

The more lines you do the darker the shading becomes.

Of course, I just clicked this link off the home page. It could have a whole other slang meaning I don't know.

Neatly spaced usually diagonal lines to indicate different shades or shadows in a black and white pen and ink drawing.
Use crosshatching to show the shadows.

Crosshatch

(v): To take something that was previously boring, unoriginal, or old, and visually revitalize or renew it.
(v): I crosshatched my plain black dress with a purple trim along the bottom and a gold snake embellishment on the neckline.

The shop crosshatched the front window, and it looks great.

Can you help me crosshatch my fashion-style?

This place needs a serious crosshatching.
