I am 21 years old have bought my first house in Virginia Beach, VA. I am what you all would call a do-it yourselfer! Ihave been doing a total renovation to my house not cause it needed it but because I wanted to. The house is only a few years old. Anyways I would like to construct new countertops out of concrete. I just think the imperfectness about them is genius to my contempory theme. I want them to have a brownish walnut tan color to them, and from you all I would like a complete how-to for them leaving no mystery for me. As detailed as you can make this for me would be great.
