My wife and i recently painted our babies room in anticpation for the big day with Ralph Lauren textured paint. She then decided that she wanted to put up a wallpaper border. We sanded the area where the wallpaper would be and wiped the wall clean. The wallpaper came with adhesive already on it so all we had to do was put it in water and apply. After putting the wallpaper up the edges did not want to stick very well. Does anyone have a suggestion?
