First step, take the cover off the bowl and place down where you want to start building. Layer the blocks in a circle around the cover.
Second Step, just start layering the next level, staggering them from how you built the first layer. Each layer will take 16 blocks for this particular bowl, which was 35" across.
This is what it will look like once you have all four levels complete. You can do 3 layers, but we wanted it a little bit higher. 
Next, if your fire pit came assembled (as did ours, since it was the last one, a perfect floor model that they took $30 bucks off, score!) you will need to take the legs off it, so you are just left with the bowl. Place the bowl on top of the rock layers, making sure that the lip has enough overhang.
Eventually we would like to get some snazzy furniture to put around this, but for now, these $17 ace hardware adirondack chairs will have to suffice. We haven't lit it yet, I think we will christen it next Friday night when we have family coming over for my husband's birthday.
Cost breakdown:
64 Lowe's rocks - $2.48 ea+, minus 10% coupon I had = $143
Lowe's fire pit - $60
Adirondack chairs - (we already had two!) $34
Total Spent: $237, which I don't think bad, as alot of people I know have fancy installers come and built them one. Another plus? Its totally moveable since it doesn't have to be cemented down. So when we finally figure out next spring what we want to do with our yard, it can easily be transferred.
