I am probably driving you crazy. I really apologize.
Good Morning Alex! You can never drive me crazy. I welcome your input. Now that I can see the front of your house, I would use edges that are brown. It would look nice with the tan color of the siding. Techo-Bloc (http://www.techo-bloc.com), a concrete paver company, has a great page on concrete edges that resemble stone. You may find this page helpful too. Nancy
