I don't like mowing my lawn, so I decided if I have to do it, I might as well give myself some enjoyment. I started out with this small project, and figured if my lawn-rolling rig worked, I'd do some cooler patterns next time. One of the reasons the "roller" is so rigged is because I was too lazy to actually make one out of PVC and lead shot, which was my original plan. Now that I know this technique works, I'll probably make one like I had planned. Duct tape tends to come off too easy, but it's also easy to rig things up with it. Have fun with this, and if you can figure out some cool patterns, let me know!
Step 1: Getting some weight
When striping your lawn, the weight of the roller pushes the grass in one direction or the other. Because the blades are leaning opposite directions when you finish, the light reflects off of them differently, hence giving the appearance of stripes. Just like when you vacuum your carpet. Now, I didn't make a roller, for reasons aforementioned, but I decided to just take some weights, and duct tape them to the flap on the back of my lawnmower. If I wasn't so lazy, I would have experimented with different weights, and see how that affected the stripes, or how hard it was to push the mower, but I am, so I just went with what I had laying around.
