TURTLE Brenda Hoddinott I-08 BEGINNER: CARTOONS & CRITTERS With a focus on improving your observation skills, you first sketch Tuttle’s proportions within a simple grid, then outline him with nice neat lines and finally add shading. The following three sections guide you step-by-step through this project: SKETCHING BASIC PROPORTIONS: The drawing of Tuttle is based on a common species of box turtle. In this section, your goal is to sketch the various parts of Tuttle on your drawing paper proportionately correct. You divide a rectangular drawing format into six squares to create a simple grid to help you draw everything in its proper place. OUTLINING SHAPES AND SPACES: This section of the lesson is designed to enhance your observation skills, and subsequently refine your abilities to translate what you see into a drawing. I offer very few written instructions; rather, you rely primarily on your observation skills. You begin by erasing the grid lines, and then use a freshly sharpened 2B pencil to replace the initial rough sketch with dark, thin outlines. Your goal is to focus on drawing neat accurate lines that provide more detailed information about the various components of Tuttle. HATCHING VARIOUS VALUES: In this section, you add shading to Tuttle with hatching graduations. A full range of values from light to dark gives contrast between the light and the shadow areas. Light affects the placement and value of every section of shading in a drawing. The light source in this drawing is from the right. Therefore, the overall values need to be lighter on the right than on the left. You need basic drawing supplies including good quality white paper, different grades of graphite pencils (such as 2H, HB, 2B, 4B, and 6B), kneaded and vinyl erasers, and a pencil sharpener. 18 PAGES – 30 ILLUSTRATIONS This project is recommended for artists from age 12 to adult, as well as home schooling, academic and recreational fine art educators.

A sketch is a quickly rendered drawing that illustrates the important elements of your drawing subject with very few details. Sketching refers to the method used for creating a quick, rough representation or outline of a planned drawing subject. A sketch can also be a completed work of art. Proportion is the relationship in size of one component of a drawing to another or others. You divide a rectangular drawing space into six squares to create a simple grid to help you draw everything in its proper place. Drawing space (sometimes called a drawing format) refers to the area of a drawing surface within a specific perimeter, outlined by a shape of any size, such as a square, rectangle or circle. A grid is a precise arrangement of a specific number of squares, of exact sizes, proportionately drawn on both a photo and drawing surface. Grids help artists with numerous challenges, such as rendering precise proportions and correct perspective. If the proportions of your subject are off, no amount of beautiful shading or fancy pencil marks can save your drawing. ILLUSTRATION 08-01 1) Draw a rectangle as your drawing format. Your rectangle needs to be proportionate to mine, such as 4 by 6, 6 by 9, or 8 by 12 inches. Use a 2H or HB pencil. 2) Divide the rectangle into six same-size squares. Measure and divide the height in half and the width into thirds. Several species of animals, including some types of turtles, are in danger of becoming extinct. Too many box turtles are currently being taken from their natural habitats, and sold into the pet trade. Subsequently, consumers who buy these turtles are inadvertently contributing to the demise of the wild population. No matter how much humans love their pet turtles, the fact remains that these animals are often deprived of freedom, the company of other turtles, a healthy natural environment, familiar foods, and most importantly of all, an opportunity to breed. BE CAREFUL! Don’t press too hard with your pencils! Lightly drawn lines are easier to erase! No matter how careful you are, when drawing with a grid, accidents do happen! If you draw in the wrong squares, simply erase that section, redraw the grid lines, and keep on going!

A curved line is created when a straight line curves (or bends). ILLUSTRATION 08-02 Begin in the lower left grid square and curve the line upward and toward the upper center square. Continue this line across the upper center square, extend its end slightly downward, and then into the upper right square. 4) Add short lines that curve outward to each end of the shell. ILLUSTRATION 08-03 Did you know that a box turtle can pull its head, legs, and tail inside its shell, thereby enclosing itself in a “box”?

Take note that this line extends into four different grid squares. ILLUSTRATION 08-05 6) Complete the outline of the shell. Begin on the lower left side of the shell, and gently curve the line downward and toward the right. Then, curve the line upward to join the other side of the shell outline. Box turtles are not recommended as house pets. Sadly, many die within a year of their captivity. Without a proper diet and natural habitat, they are highly susceptible to illnesses that are often fatal.

Watch closely the location and size of this line in relation to the grid lines and the outline of the upper shell. ILLUSTRATION 08-07 8) Sketch a circular shape to mark Tuttle’s head. 9) Add an upside down U-shape as a front leg. 10) Sketch a horizontal oval below his leg to mark the location of his foot. Did you know that a box turtle’s cuisine, when living in a natural habitat, includes such delicacies as spiders, flies, worms, crickets, grasshoppers, slugs, and snails? Yummy!

Refer to the next drawing, marked Illustration 08- 09. ILLUSTRATION 08-09 13) Draw the inside edge of his lower shell. This edge actually consists of two lines, a short one to the left of his leg, and a longer one in between his legs. Did you know that the lower shell (called the plastron) of a box turtle is hinged, so he/she can close it against the inside of the upper shell (referred to as the carapace) and hide away inside?

His fourth foot appears to be hidden behind his body. 15) Complete the rough sketch by adding his eye and mouth. Refer to Illustration 08- 11.

I offer very few written instructions; rather, you rely primarily on your observation skills. You begin by erasing the grid lines, and then use a freshly sharpened 2B pencil to replace the initial rough sketch with dark, thin outlines. Your goal is to focus on drawing neat accurate lines that provide more detailed information about the various components of Tuttle. 16) Check over the proportions of your sketch and adjust any areas you aren’t completely happy with. 17) Use your vinyl eraser to erase the grid lines. ILLUSTRATION 08-12 18) Pat the entire sketch with your kneaded eraser. The initial sketch lines need to become so light that you can barely see them. Keep your pencil sharpener and sandpaper block handy and constantly sharpen the point of your pencil as you work, so your outline stays neat. 19) Carefully observe each of the following nine drawings in sequence and redraw each section of Tuttle with thin neat lines. Watch closely the curves and sizes of each line in relation to the other lines and the spaces. Remember; don’t press too hard with your pencils. These areas become impossible to touch up, and also leave dents in your paper, spoiling the overall appearance of your drawing.
