Do you have a favourite natural material? (details inside).

I have this ‘connection’ with wood. Wooden bowls, cups, bangles, beads, boxes, wooden figures, wooden picture frames, wooden puzzles… I even collect wooden blocks that are left over from my dad’s building work. I just love the feel and look of it. Just wanted to know if anyone else has this kind of a attraction? to any natural materials like wood, marble, clay etc.
