Love this! I bought this as an accent wall in my daughters room (age 7 and 9). I was a little worried it was a little too "young" for them, as it seemed more likely to go in a nursery, but they love it! This was super easy to put up and was fairly quick.
I did peel and re-position in one spot to see if it would really "re-stick" and it worked great.
I recommend a box cutter to trim edges around baseboard/ceiling/corners. Also recommend a tool to "press" or "flatten" to the wall. I used the back of my hand to apply the paper for the most part, but there were a couple areas where air bubbles tried to form and a scrapper worked wonders.
