Make a Giant Chess Board In Your Backyard, you could use this idea just as well and plant herbs in every other square to make a lovely checkerboard effect. You can stand on the pavers to harvest the herbs and the herbs can spill over them beautifully.
Any backyard- Add a pergola separately, but with style to add height. Plant some beautiful vines to cover as much or little as you want for added privacy in your backyard. Great for those with second story homes surrounding them.
