A method of applying stitching to an outer skin layer of an interior component is provided herein. The method including the steps of: a) penetrating the outer skin layer at an entry point on a first surface of the outer skin layer with a curved needle; b) exiting the outer skin layer at an exit point on the first surface with the curved needle, wherein the steps of penetrating and exiting cause a first thread to pass through the entry point and the exit point on the outer skin layer; c) grabbing the first thread with a hook located proximate to the exit point; d) retracting the needle through the exit point and the entry point while pulling a second thread through the exit point via the first thread to form a stitch; e) advancing the outer skin layer to a new location with respect to the needle and hook; and f) repeating steps a-e until a predetermined amount of stitches are applied to the outer skin layer.
