So everytime I go with a beard I have a terrible time with the top of it. Neck line is easy, but I always botch the top. I try to have the barber do it when I can but even keeping it up is hard for me. I grabbed a shavette since that's what the barber uses which definitely give me a better view of what I'm attacking but keeping a uniform curve from sideburn to mustache is friggen hard! I've almost considered using one of my kids washable markers to draw the line I want and use that as a guide. Haven't found any good video tutorials on that either. Plenty for shaving but not as much beard tweaking. Any help is greatly appreciated.
