The main usage of a grass pathway is to help one to know how to get from one point to the other. These two points can be two different points of the garden, can be the distance between the garden and the door anything. The goal is to make one reach it in the easiest possible way. Thus for an grass pathway design in a home garden creativity is a must, concentrate on making it simple yet attractive. Use brocks. Wood planks. Artificial grass or even mosaic tiles to make patterns on the ground instead of just normal pathways.
