Where can I get interesting wood?

[Ohfourfoxache]

I'd really like to make a basic, rustic mirror from knotted, knarled and generally interesting wood.

I've had a look on ebay but can't really find the sort of thing I'm after. Does anyone have any ideas?

Thank you!

Aquatic shop - they sell it for fish tanks or a beach for driftwood, or the forest .
