I look in my workshop first. I had to spend some time last week in a couple of dark corners, and was surprised at the amount of English boxwood I have. Also some apple, a bit of spalted pear, sycamore (quilted maple) some air dried beech in large dimensions - like 10x2 inches, and I had completely forgotten a stash of English oak baulks, one of which will do nicely for a project I had almost given up on for lack of any 4x4 in stock.
Even came across a wee bit of apricot, and some actual rose. further stuff too numerous to mention. You get to hoard bits of timber. For furniture, the offcuts are scrap. For model ships, everything down to the size of quarterdeck stanchions 'may' have a use, so you keep it.... - and risk domestic disaster.
For this list, it's the box that counts. A favoured and traditional material for quality such as shipyard models. Fine grain, strong, takes good detail, and works like buttah.
