Step 16: Draw the loose sleeve of Mabel Pines' sweater on the left side using the initial line as a guide. Follow the path of the line as you thicken up the shape. Draw a half-circle at the end for the cuff of the sleeve.

Step 17: Use the circle and small lines as guides to draw Mabel Pines' hand and fingers. Draw a small curved line inside the hand for extra detail.

Step 18: Use the top portion of the original circle and the right side of the right arm as guides to draw Mabel Pines' long hair. The line for her hair starts above the left eye, moves up across the head and bends down toward the right arm and loops to end where the sweater and skirt meet.

Step 19: Draw the front part of Mabel Pines' hair as a line similar to an upside-down letter V over the right eye. Draw two lines over her ear as her headband and a couple of curved lines on top of her head for the hair that sticks out in the back.

Step 20: Use the curved line on the right side as a guide to draw the right leg. Follow the path of the line as you thicken up the leg. Draw a line inside Mabel Pines' leg for her sock. Use the oval underneath as a guide to draw her shoe.
