This is a 3 piece random placement of regular Artisan Slate - not their Premier series. However to use the Premier series would be "on trend" as folks are looking for larger sized pavers, especially with a larger sized driveway - it equates to "elegance!" However, for the borders we use a Holland (brick sized) paver in Charcoal and as per the pattern it gives a more defined and stately edge!

Thanks for response (I didn't see it until now). I used your driveway for inspiration and had mine done with regular artisan slate (random pattern), but created a "walkway" with the premier size using my own pattern with charcoal boarder on both sides of my driveway. It turned out pretty well I think!
