Rather contrasting values identify the edges of the object s parts according to the lights and darks created by the dominant light source. This lesson focuses on values and forms rather than lines and shapes. You use squirkles to draw the wonderful bumpy texture of an avocado with shading only - no outlining. This lesson is divided into the following two sections FINDING THE POSITIVE You examine a reference photo identify the negative space and single out the avocado as both positive space and the future subject of the drawing. ADDING VALUES AND TEXTURE WITH SQUIRKLES Each of the five illustrated steps is on its own page along with close-up views of a section of the drawing in progress and the original reference photo. The light source is from the upper left. Hence the values are lighter on the upper and left sections. You need 2H very good for light values HB great for middle values and 2B works well for dark values mechanical pencils good quality drawing paper and erasers. If you plan to use regular wood pencils instead of mechanical you also need a pencil sharpener and a sandpaper block. This lesson is recommended for beginners and artists wanting to review or expand upon their current skills as well as home schooling academic and recreational fine art educators. 9 PAGES - 17 ILLUSTRATIONS Published by Hoddinott Fine Art Publishers Halifax NS Canada - 2006 2 FINDING THE POSITIVE In the interest of simplicity the subject of this drawing is the avocado only without a background cast shadow or other visual distractions.

Negative space refers to the background around and or behind the drawing subject
