I would say you definitely need one of the books that Woody mentions - not only for the construction details but also for all the tips and advice on layout and design. I think this is what really makes or breaks these quilts and for this information, the books are invaluable. For Stack n Whack as opposed to OBW, you need one of the Bethany Reynolds books.
Also have a look here at the Topic List on the board, all the finished quilts and tops are here as well as lots of information in the topic heading about the books and the difference between the different techniques.
