Introduction
My grandmother kept her art things in a flat biscuit tin that smelled faintly of wax and old paper. On rainy afternoons she would lift the lid, and inside sat a row of stubby oil pastels, worn down to soft rounded nubs.
She never called it a lesson. She called it an afternoon. But somewhere between the grey light at the kitchen window and the steady sound of rain, I learned the two things that still hold true for every oil pastel drawing I make.
Those two things are layering and blending. If you can do those, oil pastels stop feeling like chalk and start feeling like magic.
This guide is for you if you have bought a small set, or are only thinking about it, and you want to understand how they actually work. We will go slowly. There is no hurry here.
What Oil Pastels Actually Are
An oil pastel is pigment held together with a waxy binder and a little oil. That is the whole story, and it explains almost everything about how they behave.
Because the binder is wax, the stick stays soft and faintly greasy. It glides across paper and leaves a rich, almost buttery mark.
Here is the important part: oil pastels never truly dry. Unlike oil paint, they do not cure into a hard film. They stay workable for years.
That means you can come back tomorrow, soften a passage you disliked, and add more colour on top. Nothing is ever quite locked in.
How They Differ From Soft Chalk Pastels
Soft pastels are dry and powdery. They sit on the surface of the paper and dust off onto your fingers.
Oil pastels are waxy and solid. They press into the tooth of the paper and hold on.
You blend soft pastels by smudging the loose powder. You blend oil pastels by moving the wax itself, sliding colour into colour.
Chalk pastels need fixative to stay put. Oil pastels mostly stay where you put them, which is one quiet reason they suit a busy kitchen table.
How They Differ From Oil Paint
Oil paint is wet and fluid. You mix it on a palette before it touches the canvas, and it sets within hours.
Oil pastels are dry sticks. There is no palette, no brush cleaning, and no mediums unless you choose to use them.
The trade-off is control. Paint blends more smoothly; pastels blend with your hand and your patience.
For a beginner, that forgiveness is the gift. You cannot spill it, and you cannot ruin it by walking away for a week.
What to Buy First
You do not need an expensive wooden box with a hundred colours. Those are lovely, and they are not necessary.
Student-grade oil pastels are completely fine to learn on. The pigment is a little less rich and the texture slightly firmer, but the technique is identical.
A basic set of twelve to twenty-four colours is plenty. Add a single black and a single white if your set does not include them.
Black gives you depth and shadow. White lets you lighten, soften, and pull highlights without reaching for a new stick.
If you want to spend a little more, spend it on paper rather than a bigger set. Good paper will teach you faster than extra colours ever will.
Choosing a Surface
Paper matters more with oil pastels than with almost any other medium, because the surface has to hold the wax.
You want paper with tooth — a fine texture that grabs the pigment. Shiny, glossy, or very thin paper will simply slide your colour around.
Why Toned Paper Helps
Many beginners reach for bright white paper and then wonder why the drawing looks washed out.
Toned paper — grey, tan, or black — gives your colours something to glow against. Warm colours look warmer on tan. Lights look brighter on grey.
You also get a ready-made mid-tone already working for you. The paper itself can stand in for shadows, sky, or the calmer parts of a picture.
Black paper is dramatic and forgiving. Its dark base makes pale pastels sing, which is perfect for night scenes and candlelight.
Cheap Surfaces That Work
Fine sandpaper is one of the oldest secrets. The gritty surface holds layer after layer of wax without clogging.
Watercolour paper, the cold-pressed kind with a light tooth, also works well and is easy to find.
Heavy cardstock is fine if you prime it first with a thin coat of clear gesso. The gesso adds the grip the cardstock lacks.
Try a few of these on small test pieces. Finding your favourite surface is half the pleasure.
Layering: The Heart of Oil Pastel
If you remember one thing from this article, let it be this: oil pastel drawings are built, not painted in a single pass.
You do not fill an area once. You lay down colour, then lay more colour over it, until the surface grows rich and deep.
Start your first layers light — gentle, medium pressure. Let the paper keep some of its texture showing through.
Then add a second layer on top, a little firmer. The colours begin to mix on the paper and grow fuller.
A third layer, pressed more firmly, starts to fill in the paper's tooth. This is where the surface turns velvety and saturated.
Fat Over Lean, in Pastel Terms
Painters talk about "fat over lean". It means laying down leaner, drier paint first, and richer, oilier paint on top.
With oil pastels the idea translates simply. Begin with softer pressure and less colour. Build up toward firmer pressure and heavier, richer marks.
Work this way and your layers bind together. If you pile soft, heavy colour onto a thin first layer, the surface can slip and separate.
Because the pastel never dries, every layer stays friendly. You can always return and press more colour in.
Blending: Four Ways to Soften Colour
Blending turns hard-edged marks into something soft, quiet, and painterly. There is no single right way. There are four, and each belongs in different places.
One: Your Fingertip
Your fingertip is the most immediate tool you own, and warm skin softens wax beautifully.
Use it for skies, gentle skin tones, or any broad transition you want to feel calm.
But here is the warning you will thank me for later: too much finger blending muddies colours. Rubbing grey over yellow turns both into a dull green.
Blend lightly, and stop sooner than you think you should.
Two: A Paper Stump or Tortillon
A paper stump, also called a tortillon, is a tight roll of paper with a pointed tip. It gives you precision your finger cannot.
Use it to blend inside small shapes — the fold of a petal, the shadow under a lip, a narrow band of sky between rooftops.
Wipe the tip on scrap paper between colours. A dirty stump carries the last colour into the next, and the muddiness returns.
Stumps are cheap, and a set of three sizes will last you a long time.
Three: A Dry Brush or Cotton Bud
For very small areas and tight edges, a dry brush or a cotton bud works beautifully.
A cotton bud is wonderful for tiny blends near the edge of a shape. It reaches where fingers simply cannot.
A soft, dry brush dragged lightly over an edge softens a hard line without smearing the whole passage.
Keep one brush aside just for this job. Waxed brushes are hard to clean, so a dedicated dry brush saves real trouble.
Four: Solvent Blending
Solvent blending melts the wax into smooth, liquid washes. It looks almost like watercolour, and it changes the whole feeling of a piece.
Dip a brush into a little odourless mineral spirit, then stroke it gently across your pastel marks. The pigment melts and flows.
Use this for large, even areas that want to feel calm — a still sky, a smooth wall, the quiet water of a lake.
Odourless mineral spirits are far kinder to a small room than the older smellier thinners. Keep the lid on and the window open.
Sgraffito: Scratching Back to Light
Sgraffito is one of the most satisfying things you can do with oil pastels, and it is simple.
You lay down a colour, cover it with another, then scratch through the top layer to reveal the one beneath.
Your tools are ordinary. A toothpick, a craft knife, a pin, or the wooden end of a brush all work fine.
What you get is crisp texture no brush could fake. Grass blades, cat whiskers, tree bark, the veins in a leaf.
Try it once and you will understand why pastel artists keep a toothpick in the tin beside the black.
Where Sgraffito Shines
Use it for highlights that need a sharp edge: the gleam on a wet pebble, the rim of a leaf catching sun, a spark on dark water.
It is perfect for texture, too. Scratch warm browns through a black sky for bare winter branches.
Scratch pale lines through green to show the direction of grass. Scratch white through grey for wind moving across water.
Save it for the end of a drawing. Sgraffito is a finishing voice, and it reads best when the layers beneath it are already full.
A First Project: One Pear, Step by Step
Let us put all of it together. A single pear on toned paper is the perfect first subject — simple shape, clear light, one calm colour harmony.
Tape your paper down so it does not shift. Choose a warm tan or a soft grey. Gather three greens, a yellow, a white, a black, and a brown.
Settle in. This will take an hour or two, and that is exactly the point.
- Block in the shape. With a light yellow or pale green, sketch the pear's outline loosely. Keep your touch soft. This is only an armature for what comes next.
- Find the shadow side. Look closely at your pear. One side is lit, one side is dark. Mark the dark side with a soft green or brown, still lightly.
- Establish values. Your drawing lives or dies on value — the lightness and darkness of things — and this is where the Chiaroscuro Drawing: Light and Shadow Techniques guide becomes useful. Push the shadow deeper and keep the lit side pale.
- Lay colour in layers. Over the lit side, press yellow, then a warmer green, then a touch of white where the light is brightest. Build the shadow side with deeper green and a hint of brown.
- Blend gently. Use your fingertip on the broad side of the pear, and a paper stump along the edge where light meets shadow. Do not overwork it. A little texture is welcome.
- Deepen and repeat. Add another layer where the pear feels thin, then blend again lightly. Fat over lean: firmer and richer as you go.
- Scratch the highlights last. When the pear feels finished, use a toothpick to scratch a few bright lines where light catches the skin. That tiny spark brings the whole thing to life.
Then stop. Step back, look at it from across the room, and let it be done.
If your pear looks more like a bird's egg on the first try, that is normal. First drawings are for learning your tools, not for framing.
Fixing the Common Frustrations
Nearly every beginner hits the same four walls. Here is how to climb them.
"My Drawing Looks Muddy"
This almost always means two things at once: too much blending and too few layers.
Every time you rub colours together, they share. Blend a little less and let some marks stay visible.
Then add more layers instead. Depth comes from colour laid in stages, not from smudging.
A muddy passage can often be rescued with one bright, clean stroke on top, pressed without any blending at all.
"The Paper Feels Greasy"
Greasy, slippery paper means you have overworked it or pressed too hard.
Wax builds up on the surface and stops holding new colour.
The fix is a lighter touch from the start. Let each layer harden a little by giving it a few minutes before the next.
If the paper is already clogged, scratch it gently with a stiff brush to give the wax something to grip again.
"My Colours Look Dull and Flat"
Flat colour usually means your darks and lights are too close together. The picture has no contrast to make bright colour sing.
Push the shadows deeper. Add a true black or a dark blue in the darkest corners.
Then lift the lights with white, cream, or pale yellow. The space between light and dark is what makes colour feel alive.
One strong light and one strong dark will do more for your drawing than five new colours.
Protecting a Finished Piece Without a Frame
Oil pastels are more stable than chalk, but they can still smudge and collect dust on the surface.
A light mist of fixative spray helps. Hold the can well back and use several thin passes, never one heavy coat.
If you keep work in a sketchbook, lay a sheet of glassine or tracing paper over each drawing before turning the page.
For stacked drawings, glassine paper is the quiet hero. It keeps wax off other surfaces without touching the art itself.
And if a piece matters to you, frame it under glass with a small mat so the surface never presses against the glazing.
A Few Quiet Words to Close
My grandmother's tin is mine now. Some of those pastels are worn down to almost nothing, and I still cannot bring myself to throw them away.
What she really left me was not the box. It was the idea that a rainy afternoon is enough time to make something, and that the making does not have to be good to be worth it.
Oil pastels are kind for exactly this reason. They forgive. They let you layer over yesterday's mistakes and blend your way toward something a little kinder.
So find a sheet of paper, a few colours, and a patch of light. Start with a pear. Scratch in a highlight. Then leave it on the table for someone to find.
