Some hardwoods are becoming very hard to find and are being harvested without concern to their eventual extinction (Brazilian rosewood comes to mind). Not only is this hard on the environment, it drives the price of the wood so high that making furniture out of it is out of the question for most woodworkers. If you can, try to buy wood from a sustainable forest (commercial tree farms that ensure the supply of the wood). Check out the National Hardwood Lumber Association for ways to support sustainable forestry.
Please read through the entire plan and all comments before beginning this project. It is also advisable to review the Getting Started Section. Take all necessary precautions to build safely and smartly. Work on a clean level surface, free of imperfections or debris. Always use straight boards. Check for square after each step. Always predrill holes before attaching with screws. Use glue with finish nails for a stronger hold. Wipe excess glue off bare wood for stained projects, as dried glue will not take stain. Be safe, have fun, and ask for help if you need it. Good luck!
