It takes some time and thinking to put together but once it is completed it looks amazing!! I cuted all the pieces following the identification letters (a,b,c etc) and put it up in the wall with tape, before peeling the decal, to see how the layout will look. The I went piece by piece pealing it and putting it on the wall. It took me like half an hour to put it together and a lot of patience. But My daugher loves it and I do too. I will totally buy it again.
