Grainlight for Procreate Quickstart Guide

Welcome to Grainlight!


This pack brings you 59 handmade brushes designed for bold lines, crunchy textures, and playful stippling. It’s all about having fun while you draw—whether you’re sketching characters, shading storybook scenes, or just experimenting with grainy chaos.

If you’re new to installing brushes, don’t worry—Procreate 5.4 introduced a brand-new Brush Library system, and we’ve put together a quick installation guide for you, RIGHT HERE.

1. Mono Liners

Mono Liners are all about steady lines with a bite. They give your strokes a grainy, slightly shaky edge—perfect for adding teeth and personality to your base shapes. Great for clean outlines, but even better when you want that vintage, hand-drawn vibe without going too stiff.

But these aren’t your average liners—they’ve got a trick. Mono Liners respond to the speed of your Apple Pencil, so the faster you move, the more natural and organic the line feels—just like drawing with an old Rapidograph or Micron pen. Each brush also comes in multiple sizes, giving you different personalities to play with. Think of it as having three brushes packed into one.

Even the simplest shapes come alive with Grainlight’s Mono Liners. That subtle jagged edge turns flat circles into characters with grit, charm, and personality.

With only Mono Liners and a few simple shapes, you can build instant illustrations that feel raw and alive. The crunchy edges and imperfect strokes give your drawing a handmade print vibe—quick to sketch, but full of punch.

See how the line changes just by varying the speed of your Apple Pencil? These brushes let you sketch with a natural flow, turning quick doodles and studies into energetic line work that feels alive. Perfect for fast ideas, character drafts, or warming up.

Pro Tip: Try speeding up your strokes—Mono Liners respond to velocity, giving your lines a natural wobble, like an old Rapidograph.

Here’s another quick test: just simple shapes and a few playful strokes. The result feels naïve, almost like a 1950s UPA cartoon. Let your hand flow naturally and see how Grainlight’s Mono Liners respond dynamically, turning casual doodles into lively little characters.

2. Groovy Liners

Groovy Liners are pressure-sensitive inking brushes built for textured, dynamic strokes. Like the Mono Liners, they shine when you want bold lines with personality—perfect for indie comics, Sunday strips, or even experimental sketches with a vintage belle époque flair.

With the new brush dynamics in Procreate 5.4, these liners kick things up a notch, responding more naturally to your Apple Pencil. For example, FT Doppler (Fig.1) plays with brush tip spacing as you ease up on the pressure, giving you airy, organic strokes. By mixing pressure and velocity, you can unlock a wide variety of textures and rhythms (Fig.2). Even fixed shapes (Fig.3) benefit—you can keep their form while adding a playful wobble and extra dynamism.

Brushes like FT Doppler are real Swiss-army liners. With a light hand, you’ll get steady, almost clean strokes—but push them with more energy, and they explode into raw, expressive lines where every mark feels alive. These tools are built to behave like the real thing, reacting to your every move and rewarding you with strokes full of personality.

Brushes like FT Fuzzy Gloop are your go-to for bold, crunchy strokes. But here’s the twist—“abuse” it with quick, downward flicks, and you’ll unlock a gorgeous hand-crafted texture, like the one in Fig.1. It’s messy in the best way, turning a simple liner into a full-on texture maker.

Pro Tip: Push Fuzzy Gloop past its comfort zone—fast downward strokes turn it from a liner into a handmade texture machine.

Each Groovy Liner has its own personality—some are scratchy, some are bold, some feel like they’re about to dance off the page. Take them one at a time, get a feel for their “vibe,” and you’ll quickly learn how each brush can set the mood for your drawings.

3. Pressure

Pressure Stipplers flip the script—these brushes don’t just react with opacity or flow. Instead, your Apple Pencil’s pressure controls the very density of the grain. Press lightly for a dusting of speckles, or lean in to build up into a gritty, semi-solid texture. It’s like sculpting your shading, dot by dot, in real time.

Each Pressure Stippler already packs a range of textures on its own, shifting from airy grains to dense shading with nothing but pressure. But the real magic happens when you mix them—layering different stipplers together gives you endless natural variations, from subtle dustings to bold, grainy atmospheres.

In Fig.1, the rock starts as nothing more than a blocky silhouette with some leafy shapes around it. Simple and flat, like cutouts on a page.

Now look at Fig.2: with just a few quick passes of the FT Sunzal brush, the whole form comes alive. A couple of downward strokes are enough to lay down a soft, grainy shadow, while some curved, harder strokes on the right edge push the contrast and carve out a harsher shadow.

That’s the magic here—you don’t need dozens of steps or layers. Just a few well-placed strokes and you’ve got instant volume, turning flat shapes into textured, storybook-ready forms.

Pro Tip: Mix soft shading with sharper accents. Use the lighter, downward strokes to define mass, then hit strategic spots with stronger curves to guide the eye toward the most important areas of your drawing.

4. Stippling

The Stippling brushes in Grainlight are your shortcut to one of the most time-consuming shading methods out there. Instead of placing endless dots by hand, these fixed brushes give you controlled stippling effects in seconds. Each brush generates its own flavor of random dot patterns, so you get natural variety without repeating textures. Whether you’re shading a character, an object, or a full background, these tools can save you 10x the effort while still keeping that handmade, hard-shaded look intact.

When working with stippling brushes, think of them as shortcuts to big impact. In Fig.1, instead of dotting endlessly, you can lay down a quick zig-zag motion to cover large areas fast. For more controlled shading and contours, use steady strokes that follow the shape of your subject (Fig.2). Each brush in this category reacts a little differently, so don’t be afraid to experiment—some are better for dense shadows, others for softer gradients. Play around until you find the technique that feels natural to you.

You don’t have to stick to just one stippler at a time—layering brushes can unlock far richer shading effects. In this example, FT Mono Shader lays down the base texture, while FT Haste adds a denser, noisier layer on top. The mix gives your shapes depth and variety without extra effort.

Here’s a comparison on how stippler brushes can transform a simple composition.

In Figure 1, the illustration is built with basic flat shapes, using mono liners and Procreate’s flood fill tool. It’s clean, but still feels very graphic and minimal.

In Figure 2, with just a few strokes and the help of clipping masks, the same base evolves into a charming nature scene. Stippling brushes add:

  • Texture & Depth: scattered dot patterns break the flatness and create a sense of volume.
  • Variation in Tone: darker and denser stippling suggests shadows, while lighter areas add highlights.
  • Organic Details: subtle veins and irregular speckles make leaves feel more alive and less mechanical.
  • Atmosphere: the added grain gives a natural, tactile mood, closer to traditional printmaking.

The result shows how a flat graphic can quickly turn into a rich, storybook-like illustration with personality and dimension — without changing the overall composition.

By experimenting with the different size presets, you can control the level of detail each brush produces. Larger presets give you bold, harsh textures, while smaller ones create a fine grain. Mixing these sizes together adds depth and variety, resulting in a more natural, organic effect.

Using Clipping Masks

To keep your textures neatly contained within a shape, you can use a clipping mask. First, create a new layer directly above the shape you want to work with. Then, tap on this new layer and select Clipping Mask from the menu. 

This tells Procreate to “clip” everything you draw on that layer so it stays inside the boundaries of your base shape. Now, whether you add stippling, shading, or any kind of texture, it will remain perfectly aligned with your target shape without spilling outside.

5. Textures

Texture brushes work almost identically to stippling brushes, but they’re designed to cover larger areas more quickly. Instead of building up fine detail with tiny dots, these brushes apply broader, less detailed textures that instantly break flatness.

When you overlap strokes, they create different fixed density levels, allowing you to suggest shadows, highlights, and depth in a very organic way. This makes them ideal for filling backgrounds, shading bigger shapes, or adding a tactile surface without having to rely on countless stippled strokes.

6. Fills

Grungy Fills give your artwork a groovy, printed-edge vibe that’s perfect for chunky textures and retro-inspired illustrations. These are fixed fills, meaning you can paint over the same area without altering the texture. This makes them especially useful for building large shapes or achieving a block-print style look.

The set ranges from noisy grains to fuzzy speckles and photocopy-style grit, each adding a unique layer of character to your fills. 

By overlapping them on Multiply layers, you can easily recreate the look of riso or screen-print effects—complete with imperfect edges and vibrant, layered color. Whether you’re after a bold vintage poster feel or subtle surface grit, these fills instantly break flatness and add a tactile, hand-printed charm.

Built for Each Other

If you enjoy the raw, handmade vibe of block-print textures, our The Basement pack is the perfect companion to Grainlight. Inspired by vintage block-print and DIY printing techniques, The Basement delivers gritty, monochrome textures that echo the charm of homemade prints.

Paired with Grainlight’s dithered fills, the two packs expand and complement each other beautifully—letting you layer, mix, and experiment your way into bold, print-inspired illustrations with endless variety.

Have fun with Grainlight

At the end of the day, Grainlight is all about play. We invite you to experiment, layer, and push these brushes in unexpected ways—whether you’re after subtle textures, bold fills, or something completely new. However you use them, we hope this pack sparks ideas, unlocks new techniques, and most importantly, helps you have fun creating.
