With any pocket hole system, you need to avoid thinking in traditional ways and begin to think and plan "Upside Down and Inside Out". The reason for this, is with projects like tables, bookcases, and cabinets, the pocket holes often want to be placed on the underside of the project so they cannot be seen and for the assembly, it's often best to work from the inside out because in many cases you are working in a confined area and don't always have the room for inserting and tightening screws.
