Figure 1. Some Langer’s “cleavage lines” run oblique or perpendicular to the recommended “main folding lines” on forehead, lower abdomen, buttocks and extremities (A); on the other hand, some Langer’s cleavage lines run parallel to the “main folding lines” over neck, shoulders, upper abdomen and back and therefore correctly in the direction of the proposed “tension lines” (B) (both figures are reproduced with permission from Lemperle et al.^[11].); langer punched round holes into cadaver skin at various sites to determine invisible “cleavage lines” (C) (Drawings by Mark Moore 2011)
