Easy to put up. I put a shallow amount t of water in my tub and dunked it in, then let it sit on my kitchen table for a few minutes before applying it to the wall. I cleaned the wall really well, then stuck it on. Because its a wet application, you have some time to slide it into place before it gets really tacky. 

You can see the color of the wall behind, through the paper at first but as it dries it goes back to white.
