The woods I use
Most of what I make comes from a local sawmill's offcut pile — oak, walnut, sapele and iroko, sold cheaply because the pieces are too short or too odd for anyone building kitchens. It's very good timber that was about to be firewood.
The exotics are different. Those I buy properly, in small blanks, and they only go into pens, because a pen uses about the volume of a fat marker and a coffee table would cost somebody's mortgage.

A note on where it comes from
The home timbers are British or European and come from a sawmill twenty minutes away. Buying their offcuts is the cheapest possible way to get good hardwood and it uses up timber that would otherwise be burned, which I'd claim as an environmental virtue if I hadn't started doing it purely because I'm tight.
The exotics are bought from established UK suppliers in pen-sized blanks. I don't buy anything CITES-listed, and I use so little of it that a single blank of snakewood will last me a year.
