Basically all I mean is the sides and back that you see in this pic. It seems like they’re simply just cut shorter than the top, meaning I would just take a number 3 guard and go straight up and down or something? Or is this cut with different guard lengths? Do I have to do a special “flick-out” motion? I genuinely am just so scared of messing up and don’t know where to begin because self-barbering seems like rocket science to me.
