timber hatch patterns?

I am taking an autocad class and was wondering if anyone has nice colored hatch patterns for pine like wood?

I am searching the net obviously but have to go through 1 by 1 to realize many of them are not so nice.

LOL....I haven't found any nice ones either.....SU has a ok one that represents pine pretty well....but because it dupicates the knot pattern over and over...its not so hot.
