Doorframes and textures (part one)

I was looking at an old doorframe in my garage at home, and I started thinking about it's texture and where it might have come from.  The frame, like most doorframes, is made of wood.  It is an organic thing that was once living and was once a tree.

Clockwise: 1) An interesting and inspiring image portraying the relationship between organic life and man-made, inanimate objects.
2) A close-up study of the texture of the doorframe, done using oil pastels and scraping.
3) A rubbing of the wood.  4) A charcoal close-up.
