With the stitching activity, observe the person's ability to retain an image using directionality as well as difficulty in three-dimensional space. While doing the single cordovan stitch, the person goes from front to back, and front to back again, with the tip to the left at least twice, but the person does not tighten in sequence.
ACL 4.8 displays an awareness of directionality that is absent in ACL 4.6.
