Thanks Ellied, Dunfermline isn't impossibly far from us so that will be a good mission for a sunny day.
We used to use Boddies of Boroughbridge in Yorkshire, which we found when we lived there. Then later we travelled frequently up and down the A1 so always stopped in. They had some amazing stuff. I was beginning to worry about where they sourced their wood
, when they realised themselves it wasn't sustainable. Now there is very little variety, and the tropical hardwoods are no longer sold there. The business seems to have shrunk, or they've changed track a bit, and anyway we no longer travel the A1, so it's good to know where to try up here.
