We had a beautiful model who for reasons that I can never really understand was having huge tattoos engraved on her side, bottom and feet. I suppose we all want our bodies to be works of art. I really struggled with this pose. First I drew it in pencil. Then went over it with water soluble crayon which didn’t work at all. Finally I dragged a stick of charcoal on its side all over it,followed by white chalk for highlights and finally conte crayon for details. It finally started to work. Never give up.
