I am an avid recycler and most of the things(if not all) I have made have been made from odds and ends of wood that have come into my possession (floorboards ends of 2x4's etc), but all of the wood has been softwood. I would love to try using hardwoods, but wouldn't have the faintest idea of how to identify them. Can anyone recommend a good book on the subject of wood identification. I would be most grateful !!
