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

SKETCHING BASIC PROPORTIONS

In this section, your goal is to sketch the various parts of Tuttle on your drawing paper

proportionately correct 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

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!

3) Draw a curved line to mark the position, size, and shape of the upper section of Tuttle’s shell

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”?

ILLUSTRATION 08-04

5) Add

another

curved line

on the right

to mark the

location of

the opening

of the shell

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

7) Sketch the

outline of the

edge of the

lower section

of Tuttle’s

shell

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!

ILLUSTRATION 08-08

11) Sketch an

oval to mark

the position

of Tuttle’s

other leg

12) Connect this

leg to the edge

of the upper

shell with a

curved line

Refer to the

next drawing,

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?

14) Sketch ovals

as his other

two visible

feet

His fourth foot

appears to be

hidden behind

his body

15) Complete the

rough sketch

by adding his

eye and

mouth

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

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

HATCHING VARIOUS VALUES

In this section, you add shading to Tuttle with hatching Hatching is a series of lines (called a set) drawn closely together to give the illusion of values Values are the different shades of gray

created when you draw by varying both the density of the shading lines, and the pressure used in holding various pencils A full range of values from light to dark gives contrast between the light

and the shadow areas Contrast refers to the comparison of different values when put beside one another, and an invaluable tool for heightening the effects of composition

Light affects the placement and value of every section of shading in a drawing Light source

refers to the direction from which a dominant light originates The placement of this light source affects every aspect of a drawing The light source tells you where to draw all the light values and shadows 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 Keep the following in mind:

Draw some hatching lines close together and others farther apart

Press lightly with your pencil for light lines and apply more pressure to achieve darker lines Keep a pencil sharpener (and sandpaper block if you have one) handy so you can easily keep your pencil points nice and sharp

Always place a piece of clean paper under your hand as you draw to protect your drawing from accidental smudges

Watch closely the directions in which the hatching lines are angled

20) Outline the various parts of Tuttle’s eye, including the highlight, iris, and pupil

Refer to Illustration 08-22 Highlight refers to the brightest area of a form where light

bounces off its surface and is usually the section closest to the light source Iris of an eye is the colored circular section of the eyeball surrounding the pupil Pupil of an eye is the

darkest circular shape within the iris

21) Add shading to his eye (as explained in the following instructions and illustrated in the next set of drawings)

Fill in the pupil with a 6B pencil (Illustration 08-23) Remember to leave the highlight white! Use HB and 2B pencils to add shading to the iris (Illustration 08-24) Take note that the values are darker around the edges, on the right, and under the eyelid Add some eyelashes on the left (Illustration 08-25) Turtles don’t really have eyelashes, so you can leave them out if you want your turtle to look more realistic Use an HB to shade in the whites of the eyes on either side of the iris (Illustrations 08-26 and 08-27)

ILLUSTRATION 08-26

BE CAREFUL! Try not to touch your drawing paper with your fingers or hands where you plan to add shading The powder component in graphite works like the fingerprinting powder used by criminal investigative sections of police departments Your skin may transfer oil to the paper, which sometimes becomes visible after you add shading, spoiling the overall look of your drawing; hence, another reason to keep a piece of scrap paper under your hand while you draw

22) Use your HB pencil and hatching lines to add light values to the various parts of Tuttle

The overall shading is darker on the left than on the right, and to keep things simpler, the hatching lines are mostly straight rather than curved Rely on your observation skills to differentiate between the very light and slightly darker sections of light shading

ILLUSTRATION 08-28

Did you know that some box turtles can grow to be more than six inches long (but most are smaller)?

Did you know that a box turtle can kill a human? Many box turtles love to eat poisonous wild mushrooms While these mushrooms do no harm to the turtle, people who inadvertently eat the turtle meat can subsequently become very ill, and very often succumb to the poison and die

23) Use a 2B and 4B pencils to add medium and dark values to the shadow areas in the sections of the drawing that are farther away from or blocked from the light source 24) Add horizontal hatching lines under and to the left of Tuttle as the cast shadow

A cast shadow is a dark section on a surface that receives little or no light The values of a

cast shadow are darkest right next to the object and become gradually lighter farther away

ILLUSTRATION 08-29

Did you know that a few Box Turtles are alleged to have lived for more than a hundred years? However, this theory is challenged in that box turtles older than fifty are rarely found in the wild It is more likely that a box turtle’s life span is between thirty-five and fifty years

25) Use a 4B pencil to add dark shading to the sections of the cast shadow that are close to the turtle

26) Examine your drawing both close up and from a distance, and touch up any sections

of shading you aren’t happy with

To make a section of shading darker, simply add more hatching lines in between the existing lines

Use your kneaded eraser to gently pat any sections of shading that you feel are too dark

ILLUSTRATION 08-30

If you like turtles and care about their future existence, you should respect their need to continue living within their natural habitats in the wild However, as long as you protect their environments, there’s nothing wrong with hunting for turtles armed with a sketchbook or a camera

BRENDA HODDINOTT - BIOGRAPHY

As a self-educated teacher, visual artist, portraitist, forensic artist, and illustrator, Brenda Hoddinott utilizes diverse art media including graphite, technical pen, colored pencil, chalk pastel, charcoal, conté crayon, and oil paints

My philosophy on teaching art is to focus primarily on the enjoyment aspects while gently introducing the technical and

academic Hence, in creating a passion for the subject matter,

the quest for knowledge also becomes enjoyable

>Brenda Hoddinott<

Born in St John’s, Newfoundland, Brenda grew up in the small town of Corner Brook She developed strong technical competencies with a personal commitment to self directed learning, and the aid of assorted “Learn to Draw” books During Brenda’s twenty-five year career as a self-educated civilian forensic artist, numerous criminal investigation departments have employed Brenda’s skills, including Royal Canadian Mounted Police and municipal police departments In 1992, Brenda was honored with a commendation from the Royal Canadian Mounted Police, and in 1994, she was awarded a Certificate of Membership from “Forensic Artists International”

Her home-based art career included graphic design, and teaching recreational drawing and painting classes As supervisor of her community’s recreational art department, Brenda hired and trained teachers, and designed curriculum for several children’s art programs In 1998, Brenda chose to end her eighteen-year career as an art educator in order to devote more time to writing, drawing, painting, and developing her websites
