Sharpie Wallpaper Tutorial- Guest post by Avery
I used a water-based Sharpie paint pen. You can find them at any craft store.
Once the vertical lines are drawn, you start drawing the slanted lines. I started in the middle of my wall. I took my measuring tape out to 16 inches and tipped it until it fit between my 14 inch lines. I made a dot on both sides and connected the dots.
