I have done this with one wall in a bedroom. you buy liquid startch and use a brush around the top of the wall and a roller just like painting and put the startch on the wall. The put your fabric (dry) on the wall and rub out bubbles with a damp sponge. after you have a section on go over it again with the startch roller. My fabric has been up for six years with no proble. It isn't messy either. When you want to take it down just spritz the fabrick with water.
