Ok so always use my thinning shears to do shih tzu faces and a new client who usually gets her dog's face clipped came in today and wanted the face really short. Well I figured I could do it with the shears but she called later to say although I had done a nice job she would have liked it shorter so I should have clipped it. The problem is I am scared to do it. I feel like I won't get a nice finish or I will make a hole or there will be a cowlick or something. I always find that faces look so bald when they are clipped. I think I am just nervous because I have never done it before maybe. Any instructions or tips to help? Thanks!
