We put this above the crib and it wasn't too hard to apply. The stickers come in sections so you need to pay attention to where the letters go from the picture that is included. We also used a level to make sure it was straight. Definetely need two people to help put this up. But if you screw up the sticker comes up easily to reapply. The only complaint I have is that it is sometimes hard to read it in certain light due to the light reflecting off of the stickers.
When I did my son's nursery over a year ago, I really wanted these, but I didn't feel the price was worth the purchase at the time when I had so many other things to buy. I finally ordered these this week, but I was a little disappointed when I got them because they are slightly different than pictured. The picture shows that they have ties at the top, so you could adjust the length if needed, but the hanger is actually just a strip of cloth with no tie at the top. Also, I felt that the "All Star" and "GO TEAM!' embroidery on the blue and tan pieces were not as thick as it looks in the picture. Truthfully, it looks like it's missing the top layer altogether because you can actually see the background color through the white stitching. They're still really cute, but probably not at full price.
