Such paths are also very cozy and zen looking and add to the relaxing charm that a yard and garden should provide. These paths are also very forgiving and flexible. Maintenance is easier. If one of the pieces start rocking and need to be changed or reset, it is much easier to do. If you later decide that you want to make your path wider/narrower, or add/remove a section, these changes are much easier to make. And if one day you decide to completely remove it, most of the stones can be reused in another project.
