I am planning to build a replica of Stickley's No. 700 bookcase. It is a relatively simple design, and I am using Robert Lang's book with shop drawings for the bookcase. I did a neatline calculation and came up with a little less than 41BF. I would like to purchase the wood once (and hopefully from the same tree). I am looking for suggestions on what I should allow for waste. I am thinking 20% but would appreciate input.

Thank you,
