Plan the application. Measure twice, draw a line to guide you, and go slow.
I applied this to my son's wall today and it was, thankfully, easier than expected. I first figured out exactly where my son wanted it, then used a 4' level to draw a faint line with a pencil. Carefully I peeled the paper off the decal then, using the pencil line as a guide, applied the decal to the wall from the bottom up and left to right, smoothing out bubbles and correcting wrinkles as I went. Next I peeled off the backing paper very slowly, inch-by-inch as my little boy peppered me with queations about why I was going so slow, how long would the sticker last, and did I need any help.<br />? At last it was done and he was super happy. I'm hopeful it stays on the wall at least as long as his interest in Minecraft last.
