We were so excited to put this border up in our sons new Lightning McQueen room. We had done a border before in his nursery, and it was no big deal. This product, however, was a disaster! It would not stick!! The walls were freshly painted and clean. We even let it hang for a day to straighten out. We even tried using border paste (even though it is supposed to be self-adhesive border)... still nothing!We were able to take the product back to where we bought it and the lady there even said she couldn't get it to work for her.Bottom line: Don't waste your time or money.We are looking for a good rated black and white checkered border to complete the look.
