Thigh: a VERTICAL fold in the middle of the front thigh, halfway between hip and knee joints.

Triceps: a VERTICAL fold halfway between the shoulder and elbow joints, on the posterior midline of the upper arm (over the tricep muscle).

Biceps: a VERTICAL fold halfway between the shoulder and elbow joints, on the anterior midline of the upper arm.

Subscapular: a DIAGONAL fold at the back, just below the inferior angle of the scapula (shoulder blade), at a 45° angle WRT horizontal, turning clockwise.

Suprailiac: a DIAGONAL fold just above the iliac crest (front-side top tip of hip bone), at about 30° angle WRT horizontal, turning clockwise.

Axilla: a VERTICAL fold on the midaxillary line (below the armpit) at the level of the nipple.
