Setting the Foundation

Before you start stacking those blocks like a game of Jenga, you've gotta set a solid foundation. We're talking a hole about twice as wide and deep as your block. Fill that bad boy with some gravel, and you're off to a great start. Next, mix up some cement and water, and pour it into the hole. Now, place your block, and use that level to make sure it's nice and straight. Let that set for a day or two, and you're good to go.
