  2. 2 Demonstrate both techniques.
  3. 3 Students practice creating sharp and soft edges.
  4. 4 Discuss how edges affect focus.
  5. 5 Students draw a simple object.
  6. 6 Use hard edges for focal areas and soft edges elsewhere.
  7. 7 Midway check: where does the eye go?
  8. 8 Students refine edges.
  9. 9 In pairs, students describe edge use.

More information

Teach: edge, sharp, soft, blur, focus. Use frames: 'This edge is…'.

Provide guided examples. Allow blending tools.

Can students use both edge types? Can they explain focus?

Draw in sand or use finger blending.

Students may use only hard outlines.

Edge control is important in painting and drawing to guide attention.
