Ambesonne Science Peel & Stick Wallpaper for Home, Colorful Comic Pencils, 13"x100", Multicolor

Step 1: Measure the whole surface you want to cover correctly. Step 2: Start from the top, peel a few inches of backing. Step 3: Stick at the top of your wall, and leave a little extra at the top to trim later. Step 4: Slowly peel away the rest of the backing down the wall. Step 5: Finish trimming with a craft knife for a polished look. Step 6: Find the pattern's seamless matching point and repeat other steps for the whole surface. *Please, use a squeegee or ruler to smooth out the panels. (not included in the package) *If you see air pockets, please stop applying immediately. Remove the sticking part & smooth air out downward. *Please, apply to smooth, flat, and clean surfaces. Dirty, textured, and extreme heat/cold exposed surfaces can affect the stickiness of the wallpaper. *To avoid color differences, buy enough rolls at a time for the same surface
