Outfitting your lawn with a set of simple stripes isn’t that hard, and it’s good for your lawn, too. Light reflecting off of blades of grass bent in different directions create the dark and light patterns. The grass most often is bent down by the pressure applied by rollers attached to the back of a lawn mower. The pros use reel mowers with multiple rollers. You can buy striping kits for your mower, or if you’re handy and want to save some bucks, you can make one yourself with a little bit of PVC.
