First make sure all your tools are razor sharp. Much easier to cut clean lines with very sharp tools and light pressure. On many small areas I will alter a tool for that single job. Small tools work best. Wood carving chisels or small knives that come to a sharp point work well. Rotory tools tend to grind away too much wood before your know it has happened.
Work only whey you are fresh. The minute you get tired quit. One minor mental laspe and your entire job can be ruined. This, I know from personal experience.
