What a great Idea! Hopscotch made with pavers in garden or backyard. Made by purchasing 12"x12"x2" smooth gray stepping stone. Simply paint with a product such as Patio Paint, intended for terra cotta pots that stay outdoors in whatever colors you want. Be sure to dig 3 inches down to allow for paver sand so stones will lay smoothly.
Mow strips can be made from any solid material used to separate the lawn from a planting bed. They allow a law mower to trim the grass all the way to edge of the lawn without having to use a string trimmer.
