Hi, my name is Julian. And I recently tried to do a themed room for my daughter I have bought a few wallpapers over the years. But this one I got from iDecoRoom is the best quality of them all. The picture quality is fantastic The layers line up perfectly with the recommended 1cm overlap. And after wall application, the sheets do not pull off from the wall. I just want to say thanks for making product is as you promotion. And I believe I got value for my money Come with fully instructions.Lay all the paper on the ground first. Overlap is ten mm. Dry clean your wall first. Make sure it is dry and clean. Peel off the top 30 cm from your number 1 panel first. Then start top to bottom. Then slowly rolling down until finish the number one panel, and then start number two panel, and repeat slowly until all finished.
