Looks great on the wall! It took two people to hang a decal this large, and it took time to slowly pull the plastic off. First, you pull the backing paper from the image and you’re left with a big translucent sheet of adhesive with the image on it. Smooth that big sheet onto the wall and rub it thoroughly with a towel. Focus on edges of the image. Carefully peel off the protective translucent sheet, making sure the image stays on the wall.It may help to not remove all the paper backing at once. For an image this large, we rolled about 1-2 feet of the paper away as we pressed the image down. We rolled the backing paper as we went.There was a tiny gap in between part of my image, as this came in three pieces since it was so big. I used a black marker to color the wall in between the seam, and it worked great. The image is supposedly removable in case you place it incorrectly, but the sections of the image like the chimp’s hands may not come off the wall without stretching or ripping, so be careful. The large, solid areas came off easily when I was the slightest bit crooked. I hadn’t smoothed it down against the wall with pressure at that point, so that helped. Once I got it positioned correctly, I smoothed it down.Overall, I’d call this an intermediate level thing at this size, just because it takes two people and some patience.
