The document discusses various artistic techniques used to create texture and shading in drawings, including hatching, crosshatching, stippling, and pointillism. Hatching uses closely spaced parallel lines, while crosshatching adds lines at varying angles. Stippling and pointillism create textures using small dots. Examples are provided of how these techniques can be used to imply different surface textures and values in artwork. Guidelines are given for a project applying these techniques to create implied texture scales and artworks using pen and ink.
