How to make custom brush sets in digital painting.

How to Build a Custom Brush Set You’ll Actually Use

Open the brush panel in most painting programs after a few downloads and you find hundreds of entries, many with names that say nothing about what they do. A painter who knows twelve brushes well will usually paint faster and more consistently than one who has four hundred and can’t predict any of them. This article walks through how to make custom brush sets in digital painting from the brushes you already use, so the set fits your hand and your habits.

Why a big brush collection slows your painting down

Every brush you have to choose between is a small decision, and small decisions add up. If you scroll through forty similar-looking brushes to find the one that makes a soft edge, you have left the painting to do it. The scrolling itself takes seconds, but it breaks your attention on the shapes and values you were working on.

Unfamiliar brushes also behave unpredictably. A downloaded brush may respond to pressure in a way your default brush doesn’t, or it may stamp at a spacing that leaves visible dots when you paint quickly. You end up learning the tool in the middle of a painting, which is the wrong time to learn it.

A large collection also makes your marks inconsistent. When each area of a painting is made with a different brush from a different creator, the edges and textures can look like they belong to separate images. A small set that you use throughout gives the whole piece a shared mark-making character.

The goal is a library small enough that you know what each brush will do before you touch the canvas.

It is very easy to be tempted by social media advertising the best new brushes, but hold off on these for now.

Audit the brushes you already use: find your real top ten

Start with evidence of what you actually use, not what you think you use. Open two or three recent paintings and look at the strokes. If your software shows a recently used brush list, check it. If it doesn’t, keep a plain tally for a few painting sessions: each time you pick a brush, make a mark next to its name on a piece of paper or in a notes app.

Once you have the list, sort it:

  • Brushes you used often. These are your candidates.
  • Brushes you used once or twice. Note them, but they don’t make the first cut.
  • Brushes you didn’t use at all. Leave them out of the new set entirely.

Next, look for duplicates. Many painters find that three of their top brushes do nearly the same thing, such as two slightly different round brushes with a soft edge. Pick the one that feels best and set the others aside. Cut the candidate list to ten at most. Ten is a ceiling, not a target. If seven brushes cover everything you paint, seven is the right number.

Write down, next to each one, what you use it for in a few words: “laying in big shapes,” “cleaning up edges,” “hair strands.” Those notes become the basis for the job-based set later.

Pick a base brush and change one setting at a time

You rarely need to build a brush from nothing. Take a brush you already like and duplicate it, so the original stays untouched. Edit the copy.

The discipline that makes this work is changing one setting at a time. If you adjust size response, spacing and tip shape together and the brush feels better, you won’t know which change did it. If it feels worse, you won’t know which one to undo.

A simple routine:

  1. Duplicate the brush and give the copy a temporary name.
  2. Make five or six strokes on a blank canvas: a fast line, a slow line, a light-pressure stroke, a heavy-pressure stroke, and a short dab.
  3. Change one setting.
  4. Repeat the same strokes and compare them to the first set.
  5. Keep the change or undo it, and write one line about what the setting did.

Those one-line notes are worth keeping. After a few brushes you will have a personal reference of what each setting does in your software, which is more useful than any general guide, including this one.

Pressure, spacing and shape: the settings that change how a brush feels

Names and menu locations differ between programs, but most brush engines expose the same three groups of settings. These do most of the work in how a brush feels.

Pressure response

Pressure response controls how your pen pressure maps to size, opacity or both. A soft curve reaches full size or full opacity with light pressure, which suits sketching and loose blocking in. A firmer curve needs more pressure to reach the maximum, which gives finer control over thin lines and subtle opacity changes. If a brush feels twitchy, the curve is often the cause. If you find yourself pressing hard to get any mark at all, the curve is too firm for your hand.

Many programs also let you link pressure to different properties. Linking pressure to size gives a line that swells and thins. Linking it to opacity gives a mark that builds up in layers of transparency. A brush with both linked behaves very differently from one with only one, so test them separately.

Spacing

A brush stroke is a series of stamps of the brush tip. Spacing is the distance between those stamps. Low spacing overlaps them so heavily that the stroke looks continuous and smooth. Raising spacing separates the stamps, and the stroke becomes dotted or grainy. That can be useful for texture brushes, but it is usually a problem for brushes meant for clean edges, because fast strokes can show gaps.

Shape and tip

The tip shape decides the footprint of each mark. A round, hard tip gives crisp edges. A soft tip blends. A flat or angled tip gives marks that vary with the direction of your stroke, similar to a flat bristle brush in traditional media. Rotation or angle settings control whether the tip follows your stroke direction or stays fixed. If marks look stamped and mechanical, check whether the tip rotation is locked.

Size jitter, opacity jitter and scatter add randomness. A little can make marks feel less digital. A lot makes a brush hard to control, so add these last and in small amounts.

Build a starter set around jobs: blocking in, shaping, edges, detail, texture

Most painters organize brushes by who made them or what they look like. Organizing by job works better, because it matches the question you ask while painting: “what do I need to do right now?”

A six-brush starter set covers the main jobs:

  • Blocking in. A large, fairly hard brush with pressure linked to size more than opacity. It should lay down flat shapes of color quickly. Low spacing keeps the fill smooth.
  • Shaping. A medium brush with pressure linked to opacity, so you can build form by layering transparent strokes. A slightly soft edge helps shapes sit together.
  • Edges. A hard-edged round or flat brush with a controlled pressure curve for sharpening or softening contours. Some painters use a second, softer version for lost edges.
  • Detail. A small, hard brush with a firm pressure curve and low spacing, for eyes, highlights, small accents and fine line.
  • Texture. A brush with higher spacing, some scatter or a grainy tip, for surfaces like rock, fabric or foliage. The article on creating textured surfaces with digital brushes covers how texture brushes work in detail.
  • Eraser or blender. The sixth slot goes to whichever tool you reach for to correct and smooth. This could be a dedicated eraser with a matching tip shape, or a blending brush.

These jobs follow roughly the order in which a painting is built. If you want the full sequence of stages from rough sketch to final render, the professional digital painting workflow article lays it out.

Use your audit notes to fill each slot. If you already have a brush you use for edges, duplicate it and refine it instead of starting again. If one job has two good candidates, choose one for now. You can always add the other later, but starting with exactly one brush per job forces you to learn each one properly.

Name, group and export your set so it survives a software change

A brush named “Brush 14 copy 3” is useless in a month. Name each brush by its job and its character, with a number at the start so the set sorts in painting order:

  • 1 Block Hard
  • 2 Shape Soft Build
  • 3 Edge Round
  • 4 Detail Fine
  • 5 Texture Grain
  • 6 Erase Round

Put them in a single group or set with a name that says what it is for, such as “Core Six.” Keep it separate from your downloaded packs, so you never have to search through them to find your own tools.

Then export it. Most programs can save a set to a file: Procreate uses brush set files, Photoshop saves brushes as .abr files, and Krita uses resource bundles. A backup copy in a cloud folder or on an external drive protects you from losing the set when you reinstall software, change devices or have a file corrupted.

Exported files don’t always open in a different program, and settings sometimes translate imperfectly even when they do. For that reason, keep a short text note for each brush with the values that matter: size range, spacing, pressure behavior, tip shape and what the brush is for. If you switch software, you can rebuild the set from the notes in an afternoon instead of guessing.

Test the set on a real painting and cut what you never touched

A set that feels good on a blank canvas can still fail on a real painting. Choose a piece you are already working on and commit to using only the six brushes for a full session, or the whole painting if it is small.

Keep a tally again. Notice three things:

  • Which brush you reached for most. This one is your workhorse. Check that its settings are comfortable for long sessions.
  • Which brush you never picked. Either the job doesn’t come up in this kind of painting, or the brush is wrong. If you needed that job and avoided the brush, adjust it. If you didn’t need the job, leave it for now and test on a different painting.
  • Where you wished you had something else. A gap in the set often shows up as a moment when you switched to a brush outside it or fought a brush to make it do something it wasn’t built for.

Then make changes. Remove or rework any brush that went unused for a reason you can name. Adjust the one that gave you trouble, using the one-setting-at-a-time routine from earlier. If you work with many layers, keeping them tidy also helps you see which marks came from which brush, and the guide on how to organize layers in digital painting covers that side of the process.

Keep growing the library without letting it bloat again

A personal set will grow, and growth is fine as long as it has rules. These keep it lean:

  • Add a brush only when a job is uncovered. If a new brush does something your set already does, it doesn’t get a slot.
  • Trial new brushes in a separate group. Download or build them there, use them on a painting or two, and move them into the main set only if you kept reaching for them.
  • Trade one in, one out. If the set has a size you are comfortable with, say twelve, a new brush replaces an existing one.
  • Review after each finished painting. Take two minutes to check the tally, rename anything unclear and retire anything idle.
  • Update your notes and your export. Each time the set changes, save a fresh backup so the file always matches what you actually use.

Some painters keep a second set for a specific project type, such as a landscape set with foliage and cloud brushes, while the core set stays small and constant. That works as long as each set has a clear purpose and its own name.

Pick one painting you’re working on, build a six-brush set for it using the job-based method above, and share the result in your next post or portfolio update.
