Here's an example of Pennsylvania Square Cut Flagstone.  Pennsylvania Square Cut can sometimes be hard to find.  However, when it's available it gives you a great assortment of Blue, Green & Bronze colours.  It is only available in square cut and cannot usually be found in random shapes.
  The bottom picture is Wiarton Square Cut Flagstone.  It comes in various shades of grey's and brown's. For this project we hand selected a few lighter brown pieces to give it some more character. It can be found in both square cut and random forms. This is a great example of how you can improve your plain old concrete front porch. View Before Picture
