Quick answer: Using oil pastels properly means working on a sturdy, textured surface, applying light pressure in early layers and saving heavy pressure for the top, keeping the sticks and your fingers clean between colors, and blending sparingly. Hold the stick near the tip for lines and on its side for coverage, scrape rather than erase mistakes, and store finished work under glassine because oil pastel never fully hardens.
Most frustration with oil pastels comes from treating them like crayons. They look similar, but oil pastels are softer, oilier and far more sensitive to pressure and layer order. Once you learn how to use oil pastels properly, the same set that produced waxy smears starts producing rich, painterly color.
Below are the habits that matter most: how to hold the stick, how much pressure to use and when, how to keep colors clean, which surfaces work, how to fix mistakes without an eraser, and how to care for the pastels themselves. Parents setting up art time will also find notes on supervising younger children, and if your young artist is outgrowing pastels, our guide to beginner oil painting kits for kids shows what the next step looks like.
Know What You Are Working With
An oil pastel is pigment held together by wax and a non-drying oil. Three properties drive almost every rule that follows:
- It responds to warmth. A stick warmed in your hand glides and smears more easily than a cold one.
- It never fully dries. Layers stay workable, which is great for blending and a problem for storage.
- Surfaces saturate. Each layer fills the texture of the paper. When it is full, new color skates on top.
Using oil pastels properly is really just managing warmth, softness and surface saturation.
How to Hold an Oil Pastel
Grip changes the mark more than most beginners realize.
| Grip | How | Mark it makes | Use it for |
|---|---|---|---|
| Tip grip | Hold like a pencil, close to the end | Defined lines, small shapes | Outlines, details, hatching |
| Overhand grip | Stick under the palm, held between thumb and fingers | Looser, broader strokes | Gestural marks, backgrounds |
| Side stroke | Wrapper removed, stick laid flat | Wide bands of color, texture from paper grain | Skies, large fields, underlayers |
| Broken piece | Short 1–2 inch segment | Controlled pressure, less snapping | Heavy final layers, kids’ hands |
Do not worry about breaking pastels. A stick snapped in half is two usable tools, and short pieces actually snap less under heavy pressure. Peel the paper wrapper back as needed, or remove it completely from a few colors you use on their sides.
The Pressure Rule: Light Under, Heavy Over
If you remember one thing, make it this: light pressure for early layers, heavy pressure for final layers.
Light first layers leave the paper texture partly open, so later colors still have something to grip. If you press hard from the start, the surface is full after one pass, and everything you add afterward will smear or slide.
A practical sequence:
- Layer 1 — map: Very light pressure, side strokes or loose hatching. Establish big color areas.
- Layer 2 — build: Medium pressure. Develop form with mid-tones and shadows.
- Layer 3 — finish: Firm pressure. Bright highlights, saturated accents, crisp edges, details.
Three layers is a reasonable ceiling on ordinary drawing paper. Pastel and sanded papers can take more.
Firm sticks first, soft sticks last
Oil pastels vary in softness between brands and grades. Softer, artist-grade pastels deposit more pigment and stick well to firm layers below them. Firmer student pastels often struggle to adhere over soft ones. If you mix brands, use the firmer ones underneath and the softest on top.
Keep Your Colors Clean
Muddy color is the most common complaint, and it almost always comes from contamination rather than talent.
- Wipe the stick after every color change. A pale yellow dragged across blue picks up blue on its tip. The next time you use it, it deposits green. A quick swipe on a paper towel prevents this.
- Clean your fingers. Keep a damp cloth or baby wipes nearby and wipe between blending different colors.
- Clean blending stumps. Rub them on scrap paper or fine sandpaper to expose a clean surface.
- Limit complementary mixing. Blending opposite colors (red and green, blue and orange, purple and yellow) produces browns and grays. That can be useful for shadows, but done accidentally it kills brightness.
- Work light to dark in each area. Dark pigment spreads easily into light areas. Light color on top of dark needs heavy pressure to cover.
Blending Properly (and Knowing When to Stop)
Oil pastels can be blended several ways: with fingers, paper stumps, cotton swabs, silicone color shapers, by layering colors on top of each other, or with a blending liquid such as baby oil or a dedicated oil pastel medium. Adults sometimes use odorless mineral spirits for a wash-like effect, which calls for good ventilation and is not appropriate for children.
Proper blending is selective. Blend where you want soft transitions (skin, skies, rounded forms) and leave the textured strokes elsewhere. Over-blended pieces lose their energy and often look flat and slightly dirty.
A quick test: if you cannot see any individual strokes anywhere in your picture, you have probably blended too much.
Choosing Surfaces That Work
Oil pastels stick to almost anything with texture. The question is how well the surface holds up.
| Surface | Suitability | Watch out for |
|---|---|---|
| Heavy drawing or mixed-media paper | Good all-rounder | Fills after 2–3 layers |
| Pastel paper | Very good; toned colors help | Choose the rougher side for more layers |
| Sanded paper | Excellent layering | Eats pastels and fingertips quickly |
| Cold-press watercolor paper | Very good; allows watercolor resist | Deep texture can leave white specks |
| Canvas paper or canvas board | Good; feels painterly | Primed canvas can be slick; works better with soft pastels |
| Gessoed wood or board | Very good for durable work | Smooth gesso needs a little texture added |
| Thin printer paper | Poor | Tears, buckles, oil soaks through |
Using oil pastels properly also means protecting the surface underneath. Tape the edges of your sheet to a board to stop sliding and to create a clean border.
Fixing Mistakes the Right Way
Regular erasers do not work on oil pastels. They smear the wax and can damage the paper. Instead:
- Scrape: Hold a palette knife or the edge of an old plastic card at a low angle and gently lift the top layer.
- Lift with tape: Press low-tack tape onto the area and peel it away to remove loose pastel.
- Cover: Because oil pastels are fairly opaque, you can often press a new color firmly over a mistake, as long as the surface is not saturated.
- Wipe with a little oil: On primed or heavy paper, a cotton swab with a touch of baby oil can soften and lift a small area. Let it settle before reworking.
Useful Techniques Once You Have the Basics
Sgraffito
Apply a bright layer, cover it with a heavy dark layer, then scratch lines through the top to reveal the color below. A toothpick, skewer or empty ballpoint pen works well.
Stippling
Tap the tip of the stick to build dots of color. Good for texture in foliage, sand and stone.
Feathering
Light, short, parallel strokes of one color over another. The colors mix in the eye without rubbing, keeping each one bright.
Resist with watercolor or ink
The wax repels water-based paint, so a drawing in oil pastel stays visible under a wash. This is ideal for underwater scenes, night skies and kids’ projects.
Stencils and masking
Lay a paper stencil down and stroke color outward from its edge to get crisp shapes and soft halos.
Caring for Your Oil Pastels
Proper use includes looking after the sticks themselves.
- Clean the tips. Wipe dirty tips on a paper towel before putting them away.
- Store flat and cool. Heat softens and deforms oil pastels. Keep them out of hot cars and direct sun.
- Keep them in the tray. Loose sticks rubbing against each other pick up each other’s colors.
- Save broken pieces. Small pieces are ideal for side strokes and for children.
- Label replacements. If you remove wrappers, note color names or numbers somewhere so you can reorder favorites.
Supervising Kids With Oil Pastels
Oil pastels are a strong choice for children because they need no water, no brushes and no drying time. To keep things smooth:
- Look for an ASTM D-4236 conformance statement and an AP seal on the packaging.
- Cover the table and use a smock; oil pastel transfers to clothing and furniture.
- Give younger kids short broken pieces, which are easier to grip and less likely to snap.
- Avoid solvents; finger blending and cotton swabs are plenty.
- Wash hands with soap and warm water afterward; a little baby oil first loosens stubborn color.
- Remove pastel from clothing quickly with a pre-wash stain treatment, and check the care label before washing.
When the novelty of pastels wears off, many children are excited to try real paint. Our article on choosing an oil painting set for a child explains which kit features help a beginner most.
Finishing and Storing Artwork
Oil pastel stays soft indefinitely, so finished pieces need protection:
- Let the work sit flat for a day or two to settle.
- If you want a spray, choose one labeled for oil pastels and test it on scrap first.
- Cover with glassine, which lifts off cleanly.
- Frame behind glass with a mat or spacer so the surface never touches the glass.
- Store flat in a portfolio, never rolled or stacked directly face to face.
Four Practice Exercises That Build Proper Habits
Reading rules only goes so far. These short exercises, each taking 10 to 20 minutes, train your hand to do the right thing without thinking.
1. The three-layer swatch
Draw three small squares. In the first, apply one color with very light pressure. In the second, add a second color over a light first layer with medium pressure. In the third, press a first color hard, then try to add a second one on top. You will feel the difference immediately: the saturated square refuses new color, which is exactly why light-under-heavy matters.
2. The clean-tip test
Draw a yellow stripe, then a blue stripe touching it. Without wiping, use the yellow again on a fresh area of paper. Notice the greenish streak. Repeat, wiping the stick on a paper towel first. That small habit is the difference between bright and muddy work.
3. The value ladder
Choose one color plus white and black. Create a row of seven boxes moving from lightest to darkest by layering and pressure alone. This teaches control over value, which matters more than color for making drawings look three-dimensional.
4. The selective blend
Draw a simple sphere with three values. Blend only the transition between light and shadow, and leave the background as visible strokes. Compare it with a version where everything is blended. The selectively blended version almost always looks livelier.
A Quick Checklist for Proper Oil Pastel Use
- Heavy, textured paper, taped down
- Light sketch with a pale pastel
- Light pressure first, heavy pressure last
- Firm pastels under, soft pastels over
- Wipe sticks and fingers between colors
- Blend selectively, not everywhere
- Scrape mistakes instead of erasing
- Protect and store the finished piece flat
FAQs
Do you press hard with oil pastels?
Only in the final layers. Start with light pressure so the paper texture stays open, then press firmly at the end for opaque highlights and saturated color.
Can you erase oil pastels?
Not with a standard eraser. Scrape the area gently with a palette knife, lift with low-tack tape, or cover the mistake with a firmly applied opaque color.
How do you keep oil pastels from getting muddy?
Wipe each stick after it touches another color, clean your fingers and tools between colors, avoid over-blending complementary hues and work light to dark.
What can I use to blend oil pastels?
Fingers, paper stumps, cotton swabs, silicone color shapers or a small amount of baby oil or oil pastel medium. Adults may use odorless mineral spirits with ventilation.
How long do oil pastels take to dry?
They do not truly dry, because the binder is a non-drying oil. The surface may firm slightly over time, but it remains vulnerable to smudging.
Are oil pastels good for beginners?
Yes. They need minimal setup and no drying time, and their bright, opaque color is rewarding. The main learning curve is pressure control and layer order.
Next Step
Proper oil pastel technique is mostly discipline: light under heavy, firm under soft, clean tips, restrained blending and careful storage. Practice those habits on a few small pieces and the medium becomes predictable.
