It is a thick wallpaper 'Beware' When you trim it . It comes apart. I let it dry and it didn't work well to trim. I did it as I put on the wall and it didn't trim well with sharp exacto knife and proper cutting edge. Also you can see the seems :( 
I didn't overlap. 
Such a beautiful wallpaper but disappointed. I got 2 more rolls to do the bathroom but might return because of these two issues.
