so while keeping the bulk of the beard shaped can be difficult keeping the lines in order is pretty easy. after going through a fair amount of videos the company that had the easiest to follow was LveBearded they broke it down to 3 lines. the first line being the line from your mustache to your sideburns called the top line. the Second line being the side line that just follows the back of the side burn (side closest to ear) straight down. lastly the bottom line being the under cut of the beard. you want to make this line where your neck meets your head usually just above the adams apple. the bottom line is important for giving your beard its bulk and fullness so do not shave it to your jawline.
