The McCunn method uses two reference lines. The '''Sleeve Centerline''' is drawn as a vertical line with length equal to the Valentina measurement '''arm_shoulder_tip_to_wrist_bent'''.<br> <br>
The '''Biceps Line''' is drawn at a right angle to the Sleeve Centerline with half of the length of the Valentina measurement '''arm_upper_circ''' plus wearing ease extending on each side from the center. Wearing ease is defined in the book as a fixed number (1.5" in each half of the line for a total of 3"). This line is drawn at a distance of '''arm_shoulder_tip_to_armfold_line''' from the top of the Sleeve Centerline.<br> <br>
