Why I Layer Soft Pastels Early or Not at All

SETUP, AND WORKING PRACTICE | MATERIALS AS DECISION-MAKING TOOLS, NOT JUST SUPPLIES

Soft pastels have a reputation for being indulgent. Lush. Forgiving. They’re often presented as the part of the process where everything finally starts to look “nice.” That framing is seductive, and it’s also responsible for a great deal of collapsed drawings.

For me, soft pastels are not a finishing touch. They are a timing decision.

I either introduce them early, when the surface can still accept them properly, or I don’t introduce them at all. There is very little middle ground where they behave well without consequences.

This is especially true of Schminke and Unison.

Both are exceptionally soft. Both carry a high pigment load. And both are physically honest about what happens when you put something too soft on top of a surface that’s already busy. They don’t politely integrate. They crumble. They shed. They destabilise everything beneath them.

That behaviour isn’t a flaw. It’s physics.

Pastel paper has a finite tooth. Every layer fills part of that tooth. Harder materials fill it slowly and unevenly, leaving space for adjustment. Softer materials fill it quickly and broadly. Once that space is gone, there’s nowhere for new pigment to anchor. Anything applied at that stage sits on top, loosely, waiting to fall off.

This is where beginners get into trouble.

Soft pastels feel intuitive, so they’re often introduced late, when the drawing already looks developed. The intention is usually to “soften things” or “add richness.” Instead, the surface becomes unstable. Pigment lifts when blended. Colours muddy. Edges collapse. The artist panics and either presses harder or reaches for fixative.

Neither solves the underlying problem.

Schminke pastels are the clearest example of why timing matters.

They are extraordinarily soft. Used immediately after PanPastels, they integrate beautifully. The surface is still open. The pigment has something to grip. Schminke can deepen colour, smooth transitions, and enrich atmosphere without disrupting structure.

Used later, Schminke crumbles.

It doesn’t matter how careful you are. If the tooth is already occupied, Schminke has nowhere to go. It sheds under the lightest pressure. Attempts to blend only make it worse. This is not a technique issue. It’s a sequencing issue.

Unison behaves similarly, though slightly less dramatically.

Unison pastels are soft enough that they demand respect. I use them to add depth and richness, but only once the colour story is already established and before the surface becomes congested. They are not detail tools, and they do not reward persistence. If a Unison colour doesn’t sit well immediately, forcing it will only degrade the surface.

Both materials require light pressure ethics.

Soft pastels punish force. Heavy pressure compacts pigment, fills tooth prematurely, and increases the likelihood of debris being dragged across the drawing. Light pressure allows colour to sit rather than smear. This isn’t about delicacy for its own sake. It’s about understanding how the material interacts with the paper.

Layering soft pastels late often feels tempting because the drawing looks close to finished.

That’s exactly why it’s dangerous. At that stage, the drawing’s structure should already be resolved. Introducing a highly destabilising material then risks undoing work that was functioning perfectly well. The desire to add more often comes from discomfort with stopping, not from genuine necessity.

Sequencing prevents that spiral.

When soft pastels are placed early, they become part of the foundation rather than a disruptive overlay. When they are placed late, they demand more than the surface can give. Knowing the difference saves time, frustration, and finished work.

I don’t use Schminke or Unison to rescue drawings.

I use them to support drawings that already know what they are. If a drawing cannot stand without them, they won’t fix it. They will only make the failure more expensive.

The teaching takeaway here is blunt but useful: soft pastels are not forgiving. They are timing-sensitive.

If you want their benefits, you have to give them space. That space only exists early on. After that, restraint is the smarter choice. Leaving a drawing slightly less rich but structurally intact is far preferable to pushing softness until everything collapses.

Layer soft pastels early, when the surface can hold them.

Or don’t layer them at all.

Knowing when not to add is just as important as knowing how.
