1. Use a ground

There are many benefits to working on a ground. One of these is increased painting or drawing speed. A ground covers a painting or drawing surface from the outset. It can act as mid-tone, with only black and white used to apply dark and light areas (as in the examples below) or be left partially visible in the final work. This results in an artwork that is much faster to complete (see our article about painting on grounds for more information).
An A Level Art portrait by Mariam Shafei-Sabett from Dame Alice Owen’s School, Hertfordshire, England and a teaching exemplar from Amiria Robinson:

The beautiful A Level portrait on the left has been completed upon a pale brown ground (this provides a mid-tone skin colour and is also left visible in the background). On the right, a wash of ochre, blue and brown provides a background to the drawing black and white pencil drawing.

2. Incorporate mixed media /patterned surfaces / textural elements

As with using a ground, patterned, decorative or textural items can cover areas of an artwork quickly. Although this strategy should be used with care, selecting only materials which support or enhance your project (usually with reference to a relevant artist model) this can be a great way to speed up your project and introduce creative use of mixed media.
Two AP Studio Art (Concentration) pieces by Alyssa Church from Bingham High School, South Jordan, Utah, United States:

Exploring fairy tales (the ‘Princess and the Pea’ and ‘Rumpelstiltskin’, these well-composed works allow the student to demonstrate observational drawing skills in certain areas of the artwork, while saving time by covering other areas with mixed-media patterned surfaces.

Domestic Violence series by artist Scott Waters: 

Artist Scott Waters produces gripping paintings on a range of found surfaces, including wallpaper, postcards and romantic paperback book covers. Note that the chosen surfaces are integral to the message in the work; the shattering of domestic bliss.

3. Work on several pieces at once

Working in series – completing several paintings or drawings at one time – is a very helpful strategy for Art students. This speeds work up for a number of reasons:

• A single colour can be used throughout a number of works, without needing to stop for remixing / washing brushes
• While one work is drying, another one can be worked on
• Similar processes or techniques can be mastered quickly and repeated on subsequent works

In addition, when working on several pieces at once, ‘preciousness’ about the work tends to be lost, leading to more experimentation and greater work speed.
The studio of artist Willem de Kooning:

These photos of Willem de Kooning’s studio show several works in progress pinned to the wall and scattered across the floor. Although creating a glorious working environment such as this is not possible in most high schools, many Painting classrooms have small pin board alcoves which can be used to display work in progress.

4. Paint things in the right order – background areas first

Painting things in an illogical order is surprisingly common amongst high school Art students. In almost all cases, the background should be completed first, followed by the middle-ground, ending with the foreground. This is easily understood when considering a tree in front of a cloudy sky. If you make the mistake of painting the tree first, the sky has to be meticulously painted around every leaf and branch: an irritating task that takes hours (and ends up looking a little shabby). Painting the sky first, however, means that a large brush can quickly be used to paint the sky, with the tree then easily added over the top. Painting in the correct order also results in a painting that has layers (which gives it a richness and lustre, as with using a ground). If you find that subsequent layers of paint do not adequately cover earlier ones, you have an inferior brand of paint. (We will detail our paint and art supply recommendations in an upcoming article – stay tuned)!
Note: Once you understand how to build up a painting in layers, you will realise that often this involves drawing items in stages also.
Paintings by artist Susan Danko:

These vibrant, architecturally-inspired abstract works by Susan Danko are a prime example of an artwork that must be painted in a logical order. These paintings would have been exceptionally tedious had the rays of light had been painted first.

5. Use masking tape to create straight edges

Some students are concerned that it might be necessary to ‘prove’ that a straight line can be painted by hand. This is not the case. Your control of a paint brush can be ascertained immediately by looking at the remainder of your painting. Masking tape creates straight edges in seconds. Once mastered, this trick can save you hours – and make your paintings sharper, cleaner and more professional in the process. If you haven’t used masking tape before, buy some now!
This painting is by Amiria Robinson (me):

Enlarged details of this seascape painting can be seen to the right. All of the straight lines were created using masking tape.

6. Leave artwork purposefully incomplete

Artist work is sometimes purposefully ‘unfinished’. Art students shouldn’t feel obliged to ‘complete’ every item. There are many occasions when a fully rendered drawing is not necessary. Drawings, especially those in sketchbooks, can be left with edges trailing away and tone only applied to some areas. Leaving work unfinished is particularly useful when conducting visual research, exploring ideas and experimenting with media. Depending on your artist influences, this may even be appropriate in final works – as a way to draw attention to focal points and direct attention within an artwork.
Note: This should not be used as justification for avoiding homework tasks set by your teacher!
Jim Dine’s tool drawings: 

Jim Dine is an outstanding artist to use with middle and high school Art students. His charcoal tool drawings combine precise, analytical outlines (which fade away and are incomplete in places) with perfectly rendered areas and gestural, and expressive mark-making in some of the negative spaces left around the tools.

Drawings by Megan (left), Parrish (top right) and Anna (bottom right) from the Art Department of Cedar Ridge High School, Hillsborough, North Carolina, United States:

Completed as part of the high school qualification AP Studio Art (2D Design) these drawings are purposefully rendered in small areas only, creating emphasis and directing vision.

7. Omit parts of a scene

Deliberately picking out certain parts of a scene to draw has a strong impact on the final work and must be used with care to ensure that the resulting image supports the ideas explored in your project. As with the previous option, this allows you to demonstrate strong observational drawing skills, while saving time by omitting part of the scene.
A graphite pencil drawing by Langdon Graves: 

This contemporary drawing by artist Langdon Graves involves carefully selected regions of a face: well-balanced curving forms of an ear, eye and glasses.

An A Level Art drawing by Madeleine Ferns: 

Eliminating certain areas of a scene is a dramatic measure that brings immediate focus to an artwork. This drawing by high school student Madeleine depicts only men walking down a street – with all aspects of the surrounding obscured. This immediately suggests monotony; the daily grind; living on autopilot; and carrying out the daily routine without ever stopping to notice the world passing by.

8. Selectively flatten tone

Another option that students have is to flatten tone – to remove the smooth blending gradations from dark to light. This strategy should be used with caution – and usually only in certain areas – as unintentionally flattening tone can be the hallmark of a weak student. As indicated by the artist examples below, however, there are times when all or parts of the tonal variation within an artwork can be omitted with great success.
‘No one wants to play SEGA with Harrison Ford’ by artist Brandon Bird:

In this contemporary oil painting depicting Harrison Ford, artist Brandon Bird carefully positions three realistically rendered figures and a SEGA games system upon a wide flat area of tone (interestingly this is available in prints with different coloured backgrounds). This eliminates unnecessary clutter and swiftly focuses the attention of the viewer.

Self portraits from Annemarie Busschers’ ‘Beyond Grief’ series:  

The faces in Annemarie Busschers’ self-portraits are stunningly rendered, with extreme attention given to fine details and irregularities of skin. The hair and body are pale; the hair almost completely devoid of tone. This pushes all attention to the face; the turn of the lips; the emotion in the eyes.

9. Focus on Line

There are many occasions where it may be appropriate for a high school student to draw using only line (it is often the application of tone that is time-consuming for students, so working exclusively with line can provide a welcome relief). Blind drawings, contour drawings, cross contour drawings and other hatched drawings (please see our collection of beautiful line drawings for ideas) can form an important part of your project.
Note: It is usually necessary to demonstrate an ability to apply tone at some point to examiner, so it is not wise to exclude tone from your project altogether.
A Level Art sketchbook pages by Annie Jones:  

This A Level Art project uses line to show complex architectural details; drawings applied over beautiful mixed media layers, which helps to create rich, visually interesting sketchbook pages.

Contemporary drawings by artist Federico Infante: 

These works by artist Federico Infante contain a focus on line (in this case used to create residual after-image effects) with tone applied in certain areas only. This helps to draw the viewer in to the world of the central figure, so we share the emotion of this captured moment in time.

10. Include photographs

While there is a certain quantity of painting and drawing that must take place within a Painting or Fine Art portfolio, photography can provide an excellent mechanism for moving a project forward at a faster pace.
An AS Art sketchbook page by Littlemissnoface:  

Photography can be used as a tool to develop composition, as in the beautiful AS Sketchbook pages above. Rather than ordinary snapshots of source material, the photographs here are complex digital manipulations, which help refine ideas and compositions.

In addition to helping with composition planning, photography can be collaged into artworks or used as painting ground. If the photograph remains visible in the final work, less paint needs to be applied, thus speeding up the art-making process.
Painting on photographs by artist Charlotte Caron:

These artworks by Charlotte Caron show animal faces painted on top of photographic portraits. Note the clever unity of the colours in each image.
