A pencil and paper will also be useful. Soldering irons can be a little tricky. Practice on some scrap wood first, so that you can see how slow you need to go and how hard you need to press. It will also give you the chance to figure how to move the iron, in order to get different shapes. Make sure the wood is clean and smooth.
