If you find a little bubble on your veneer furniture you can fix this without much trouble. Take a thin towel and put your iron on the area where the veneer is coming up. The heat will make the glue under the veneer warm and stick again to the area. You need to be careful not to burn the area just heat the area lightly to make the veneer stick back down. Putting a heavy book or rock on the area after it is warm will help the veneer stick while it dries!
