Take your time! This mural was not difficult to put up, but you really need to take your time. I had read other reviews on wall murals and some said they ran out of paste so I went conservative on the paste at first. Big mistake. The panels need to be saturated with paste. Since I did not do this at first I had to go back and that made things very difficult. There was plenty of paste and even had some left over. Don't be too concerned about the bubbles as they will dissapear when then mural dries and shrinks. We spent a lot of time worrying about them and trying to smooth them out. Follow the directions EXACTLY and you will have no problem with the mural. Once it's up it is beautiful!
