I just updated my review from 4 stars to 1. The wall paper seems to be shrinking as we now can see the wall between every single strip. It looks awful.  ORIGINAL REVIEW: We just put it up today and overall it was pretty easy. A section of our wall is drywall and the rest is plaster so it definitely was easier on the drywall. Some of the pieces didn’t line up exactly but not too noticeable. Now I just hope it stays up! Overall looks great, especially for the price. It took me and my husband about 4-5 hours for the one wall. Definitely use a dry eraser to smooth and a ruler and exacto knife to together to edge. Added a fun wall to our kids playroom.
