# Art Hatching and Blending

\$7.00

For this unit’s assignment, we will try two types of drawing techniques.  Each drawing is a way to create depth on a two-dimensional surface using value.  In the first drawing, we will use blending to create value.  We will use hatching and cross-hatching in the second drawing to create value.  Each drawing should be completed on a separate page in your sketchbook.  Drawing 1: Complete a 5-step value scale using blending:  On a separate page in your sketchbook, draw a 5-step value scale.  The measurement of the scale should be 1 in. by 5 in.  (Each box is 1×1 in.). The first step of your scale should be left entirely white.  Using your graphite pencil, shade the 5th square as dark as possible.

Now you will create a gradation of value in equal steps moving from white to black.  Make sure each square demonstrates a similar change in value.  We will repeat this exercise in the second part of this assignment.  You can put both value scales on the same sketchbook page I have done below. Value Scale 1 – Graphite Blending. Shows how to create a 5 inch by 1 inch table to demonstrate blending. Blending from 1 to 5, lightest to darkest shades of pencil Once you have completed your value scale, please move to a new page in your sketchbook; we will apply these values to a drawing.

Look very carefully at this image and read the following instructions.  Don’t panic!  We are going to go through this step by step!  A circle on a page indicating highlights and shadows in a drawing  Using your graphite pencil and a straightedge, very lightly draw a line across your page about ¾ of the way down your page.  This line will represent the back edge of the tabletop. Find a circle to trace!  The top of a cup, bowl, jar, or circular object.  Position the circle so that the bottom of the circle is slightly below your horizon line.  Draw this outline very lightly.  Another image demonstrating where to use highlight and shadow on a circle  Before you shade your drawing, look carefully at this example.

Where are your darkest areas?  Where are your lightest areas?  Examine the picture and decide where is the light source.  Do you notice the shadow on the sphere and the cast shadow on the table surface?  Also, look carefully at the background space.  Do you see how the value changes as we move from the left side to the right side?  The same thing happens on the table surface. Now begin shading.  Note that you can always make areas darker.  It can be a little trickier to lighten regions back to the white of the paper.   Look carefully at the below image.  Make sure that your drawing contains all of the elements mentioned below. Refer to your completed value scale to ensure you use a range of values.  Note that only the “highlight” area is the bright white of your paper.
