5: Add Shading
Use short squiggles to finish the hair. Add a dark line on the jaw for shading. Use many short straight lines on the collar of the turtleneck sweater to show ribbing. Add more ribbing to the neckline, cuffs, and waistband of the V-necked sweater. Fill in every other diamond on the V-necked sweater with straight up-and-down lines to define the knit.
Great job! This patterned sweater is perfect for a chilly day, but colder weather calls for more protection. See the next section to learn how to draw a man in a bomber jacket.
