Follow these tips when you’re starting off learning line drawings.
What Is Line Drawing?
How does a line function in line drawing? Line drawing, also called contour drawing, primarily uses the line to indicate a change of plane.
What is a change of plane? It’s the edge where two sides of an object meet. Sometimes this is very easy to see. Take a look at this box, for example. Each side of the box is a plane and you can easily see them meet. So it’s really easy to do a line drawing of the box by simply drawing all the edges.
Remember this idea of ‘change of plane’ because it’s an important one that will help your drawing.
Changes of Plane
Now that we’ve looked at a box with nice crisp edges making a clear change of plane. Here are two more boxes of sorts, but there’s a complication: the edges are rounded. The change of plane happens more gradually and it isn’t at all crisp.
Finding the Plane Changes
When the change of plane happens against the background, it’s easy – that outline is clear and sharp. But what about the edges between two planes facing us? They form a gradual curve.
Sometimes we can make a ‘best guess’ as to where the middle of the change of plane is. We can also draw as close to the edge of each plane as we can, leaving the curved area between them. Sometimes this can work quite well and the somewhat visible edges on the face of the dice mean you can get away with a solid line in this case. However, it does make the edge look much harder than it really is.
Using Implied Line
The other option is to draw using implied line. An implied line uses a slight break in the line to suggest that an edge is there, but it isn’t as strong as other lines in the drawing.
If varied line weight is being used, we can lift the pencil off and then on again gradually, or we can use a clean break or a dotted line. The brain interprets these broken lines as being less sharp or hard than the solid lines. This can help you create the effect of the gradual change of plane.
The die on the right is drawn this way, with broken lines suggesting the more subtle curved edges.
Complex Changes of Plane
So far we’ve looked at very simple objects with quite basic changes of plane. Most of the time, our subjects are much more complicated, with many different changes of plane. Some are sharp and some are very gradual.
The human face is a favorite subject and it has many complex and subtle changes of plane. Let’s take a look at this store mannequin as a slightly simplified example.
With a bit of imagination, we can visualize some planes in the face:
- The sides of the face and jaw.
- The forehead, nose, top of the cheeks and chin as the forward planes.
- The lips are tilted and the top of the head is a horizontal plane.
Of course, you can break the planes down much smaller. Studying the planes of the face in this way can be a useful exercise and this is an approach we’ll revisit in a shading exercise. But for line drawing, we really need to ignore most of these planes otherwise our subject will look more robot than human.
Tip: If you can visit an art gallery or museum, try drawing a portrait sculpture and breaking down the planes of the face. The white marble of a sculpture, without the confusing detail of real skin, makes a good subject.
Problem Areas in Contour Drawing
The tricky part when line drawing is to decide when to use a solid line to describe a change of plane and when to use an implied line.
When portrait drawing with pure contour, we almost always ignore many of the subtle planes of the face. However, even quite strong changes of plane, such as along the side of the nose, need to be toned down at times depending on the angle of the face. As you can see in this example, clearly defining that edge doesn’t work in this case.
Another problem with portrait drawing is a change of pigment: the girl’s lips are pink, but the changes of the plane around the mouth are very subtle. Outlining them like this can make them look like paper cut-outs.
Unless you specifically want an extremely minimal, crisp, illustration-style drawing, implied line is the best tool for dealing with those tricky changes of plane. Even in a strongly outlined style, you can still make judicious use of it.
You’ll often see manga illustrations that use a small line under the lip or nose or across the cheek to suggest a plane without too much detail.
In this example, only the very strongest changes of plane are outlined. Broken or implied line is then used for the softer changes of plane.
Deciding where to put the implied line is fairly easy with the side of the nose and the shape of the mouth. It’s trickier with the very gradual changes across a rounded cheek or chin. Sometimes in these areas, a couple of short marks will just suggest the contour every so slightly.
So as you can see, implied line, in conjunction with an awareness of change of plane, can help you create a more natural and three-dimensional look in your line drawings.
Continuous Line Drawing
A continuous line drawing is one in which a single, unbroken line is used to develop the image. Although mostly created as an exercise, many continuous line drawings can stand on their own as finished works of art.
As an exercise, continuous line drawing forces the artist to closely observe the perceived lines of the subject. While focused mostly on describing the contours, shadows and form can also be communicated depending on the approach taken.
Why Create Continuous Line Drawings
Aside from the fact that a continuous line drawing can be a work of art in its own right, it is also a worthy drawing exercise for developing hand-eye coordination and observation skills. As artists, we need to spend a bit of time in practice to further develop our drawing skills.
Simple line drawings such as these can be created in any environment and do not require a hefty time investment. A sketchbook could be filled with them in a matter of days. Most drawings only require a few minutes to benefit from the exercise.
Any mark-making tool can be used, but pens, markers, and graphite pencils are most commonly used.
The “Rules” for Continuous Line Drawing
While there should never be a set of rules for making art, there are a few parameters to make the drawing exercise most effective.
The first thing you should recognize is that no drawing will be perfect. With continuous line drawing, the imperfections will be very clear. However, it is often these very same imperfections that make the drawings so visually interesting. So, instead of avoiding the imperfections of the mark, embrace them and allow them to add a bit of character to the end result.
Ok, now to the “rules”…
- Once you place your pen or pencil on the surface, do not remove it until the drawing is complete. Your goal is to describe the subject with one, singular line. It can become thicker and thinner in areas, but it should never break.
- Try to move your hand at a similar speed in which you observe the subject with your eyes. This will help to create more accurate proportions and shapes. But remember, perfection is not attainable.
- Do not erase. Leave the imperfections and let them be a human element in your work. (As humans, we are attracted to artifacts that are clearly made by other humans.)
- Repeat. Do several drawings in one sitting and try different tools. You may find that you are more comfortable completing the exercise with a graphite pencil instead of an ink pen or vice versa.
*A continuous line drawing is slightly different from a blind contour line drawing. A blind contour line drawing is a continuous line drawing, but the artist does not look at the drawing surface, only at the subject.
A Suggested Exercise
Don’t be fooled. Creating a successful continuous line drawing is a little trickier than it may look. Sure, the finished result is rather simple, but the simplicity actually makes its a challenge.
Your choice of subject also plays a role. I would suggest working with a subject that will challenge you, but still has clear lines and areas of contrast to work with. Subjects in low light will prove to be difficult because all of the lines may not be clearly visible.
One subject that is always great to work with is with you all the time – right at the end of your arms. Your hands are perfect as subjects for drawing because they present an “attainable” challenge. Plus, they can be configured in endless positions.
For the above exercise, draw your hand from three different positions, but keep the pencil on the surface throughout the process. Try to draw all three hands with just one line, changing the positions of your hand while you draw. Remember, it’s okay if the proportions become a little distorted.
Why Practice is Important
Drawing is a skill that requires practice. Just like other skills, you need to exercise your mind to improve your drawing from time to time. Creating a continuous line drawing is a great exercise to just that.
So grab that sketchbook and start having some fun and improve your observational skills at the same time.
