Now for piecing it all together. I started by laying out the frame to make sure that it would line up right and make a decent looking rectangle. After seeing that the frame was all square and good I went ahead and laid out the 8 pieces for the back next to each other in a line. Next I laid the frame on top of the back panels to see what it was gonna look like. After seeing that everything was going to line up and look good I went ahead and started to screw the frame down to the back panels. I started by attaching the bottom of the frame to all of the back panels and then one side and just worked my way around until the frame was fully attached to all of the back pieces. One thing to remember while screwing down the frame is to keep your speed square close so that you can keep your corners squared up so that when you're finished your frame will look nice and even and not lop sided or anything.

When finished with attaching the frame to the back pieces you can take the two pieces you want to inset and go ahead and screw them down. The distant between these pieces is up to you. I just put them half on the first full slate and half on the second slate of the back on each side to keep them even. (The picture where the wood looks darker is before I sanded it down a little)
