Introduction: It helps to be someone who aims for the perfect job , I have seen plenty of cutting in by others that is off by quite a bit that ceiling line needs to be sharp and if your cutting a color against another color it needs to be right on . I had a customer which I am sorry I dont have her reference but she ranted about my lines in her living room she had beige and red walls and it did look nice . The other thing is being clean and polite , I am good with customers and have a knack for getting jobs.
