We just finished this beautiful flagstone pad and path, for the flagstone we used the Variegated Bluestone from Smith Rock. Our customers main problem with their yard was their chickens tearing it apart, we didn’t have too many options for a solution due to huge Sweet Gum roots spanning the length of their yard. We worked around them and got it done! The infill we used here was 3/4-1.5 river rock to minimize the migration due to chickens.
