Choosing brushes can feel overwhelming. You do not need a giant set to make great work, you just need a few well chosen tools that match your medium and your style.
This guide walks you through what actually matters so you can stop guessing and start painting.
Start with your medium
Before you think about shapes and sizes, match your brush to the kind of paint you use most. The same paint can behave very differently depending on how thick or thin you use it, and that affects which bristles feel best in your hand.
Oils
Oil paint out of the tube is usually thicker and slower drying, which is why many artists like brushes with enough spring to move and sculpt that paint. When you are working with heavier paint, a slightly firmer brush helps you push color around without the hairs folding over on you. Try Trekell's Opal or Hog Bristle brushes for this.
However, if you use a medium to thin your oils and you are chasing very smooth, almost brushless strokes, a softer brush can actually be the better choice. Softer synthetics glide over the surface and leave a more even mark, especially for glazing, blending, or finer work on top of dried layers. Trekell's Spectrum or Sienna brushes are great for this.
The key is to match bristle feel to how you personally like to handle oil paint, not just to the label on the tube.
Acrylics
Acrylics dry fast and can be used in many ways, from thin layers to thick, textured passages. Versatile synthetic brushes shine here, because they can handle those shifts in consistency over a single painting session.
If you love crisp edges and graphic shapes, you might prefer synthetics with a bit more spring, like Crimson Taklon. If you are working with thinner acrylic layers, a slightly softer synthetic can feel smoother and less scratchy on the surface, like Golden Taklon.
Watercolor and inks
Water media brushes need to hold a lot of liquid and release it smoothly. You are looking for a belly that can carry water and pigment, plus a point that snaps back when you lift pressure.
A good watercolor round should be able to make a fine point, a mid size stroke, and a wider stroke with nothing more than a change in pressure. That is what makes it so versatile for lines, washes, and details. Check our our Protege brush line that offers everything you need.
If you move between mediums, it is worth having separate main brushes for each so you are not fighting dried acrylic in a watercolor brush or scrubbing oil color with a delicate wash brush.
Brush shapes explained simply
Once your medium is clear, shape is what really changes the way your strokes look and feel. Here is the plain language version of the most useful shapes, including some specialty options Trekell artists love.
Round
A round brush tapers to a point with a full belly in the middle. It is great for drawing like lines, details, curves, and small shapes. Press harder for wider marks and lighten up for very fine lines.
This is the shape most people cannot live without, no matter what they paint.
Flat
A flat has bristles cut straight across with a wide, flat profile. It is ideal for bold strokes, blocking in shapes, and filling larger areas. Turn it on its edge and it can still make sharp, narrow lines.
If you like strong graphic shapes, a flat tends to feel natural very quickly.
Bright
A bright is similar to a flat, but with shorter bristles. Shorter hair means more control and less wobble when you are working with thicker paint.
Many oil and acrylic painters like brights for punchy, square strokes and for layering paint on top of paint without losing control.
Filbert
A filbert is a flat with a rounded tip. It softens edges and is excellent for organic shapes like faces, petals, and clouds.
Think of it as a middle ground between a flat and a round. You get the coverage of a flat with the softer edge of a round.
Angle
An angle brush has bristles cut at a slant. This shape excels at cutting in edges, reaching tight corners, and painting along curves.
It is especially helpful for painting around shapes, working into corners of panels, and creating tapered strokes in one motion.
Script / rigger
A script or rigger brush is a long, very slender round with bristles that come to a fine point. It is designed for long, continuous lines.
This shape is ideal for fine line work like branches, whiskers, eyelashes, lettering, and fluid, calligraphic strokes. Because the hairs are longer, it holds more paint than a tiny spotter, which helps you pull a line without stopping every inch.
Liner
A liner brush is similar to a script but usually a bit shorter in hair length. It still offers precision lines, but with slightly more control and less flex than a full length rigger.
Use a liner when you want clean outlines, small decorative details, and tiny highlights. It is a key shape for detailed work in both fluid acrylics and inks.
Cat’s tongue
A cat’s tongue brush is a hybrid shape with a pointed tip and a broader base, often somewhere between a round and a filbert.
This shape is very versatile. You can:
- Use the point for fine lines and detail
- Lay the belly down for broader strokes and fills
- Shift pressure to move smoothly from thin to thick in one stroke
Many artists like cat’s tongue brushes for expressive, calligraphic marks, petals, leaves, and anywhere they want both control and flow in the same tool.
Fan
A fan has bristles spread out in a fan shape. Artists often use it for blending, softening edges, or creating effects like foliage, hair, or texture.
This is more of a specialty effect brush than a first purchase, but it becomes useful once you know what kind of marks you love.
You do not need every shape on day one. For most people, a mix of a round, a flat or bright, one softer edge brush like a filbert or cat’s tongue, and a liner or script for fine lines covers almost everything.
How many brushes do you really need?
Seeing huge brush racks can make it feel like you are under equipped, but a small, intentional set goes a long way.
Trekell three piece minimal set
If you want pure simplicity, you can start with a three piece minimal set and still get a lot done. Trekell offers a three piece minimal set that is built around this idea. You can view it here: 3 Pcs Brush Set.
A simple three brush structure looks like this:
- One medium round or cat’s tongue for drawing, details, and general use
- One medium flat or bright for blocking in and edges
- One small liner or script for fine lines and signatures
With just these three, you can sketch your composition, block in your major shapes, and add details and highlights at the end.
Trekell five piece minimal set
Once you know what you like, a few extras unlock more options. Trekell also offers a five piece minimal set that gives you added flexibility without overwhelming you with choices. You can view it here: 5pc Brush set.
A five brush structure might look like this:
- Round, small, for fine details
- Round, medium, for general work
- Flat or bright, medium, for blocking in and edges
- Filbert or cat’s tongue, medium, for softer shapes and transitions
- Liner or script, small, for long lines and accents
This gives you coverage, detail, and special strokes without needing a large number of brushes.
An all media minimal set with Golden Taklon
If you want one simple set that can handle oils, acrylics, and water based mediums, a short handle Golden Taklon line is a strong place to start. Golden Taklon is a soft synthetic that plays nicely across mediums and feels smooth on panels and paper.
Even for oils, if you are using medium to thin your paint and aiming for smooth, controlled strokes, these softer synthetics work very well. They are not the stiff, bristle style brush that people associate with heavy impasto, but for many artists that softer feel is actually easier to handle.
An all media minimal Golden Taklon set might include:
- Round, small
- Round, medium
- Flat, medium
- Filbert or cat’s tongue, medium
- Liner or script, small
That handful of brushes can carry a painter through studies, finished pieces, and experiments in oil, acrylic, gouache, and watercolor, as long as they clean them properly between uses.
You can adjust sizes to match your most common panel sizes. If most of your customers use smaller panels, lean a bit smaller in brush sizes so they do not feel clumsy or oversized.
Match your brushes to how you like to paint
Technique and personality matter just as much as medium. Two people can use the same paint and want completely different things from their brushes.
If you like loose, expressive strokes
Try slightly larger brushes than feels comfortable at first. They prevent you from overworking a painting with tiny marks. Flats, filberts, cat’s tongue shapes, and larger rounds with a bit of spring can help you cover areas quickly while still feeling responsive.
If you like tight, detailed work
Choose smaller rounds, liners, and script brushes that keep a sharp point. A good detail brush should feel a bit like a pen. A short handle Golden Taklon round or liner with a fine tip is often enough to handle most detail work when you are starting out.
If you love soft blends and smooth transitions
Softer synthetics and filberts, along with cat’s tongue shapes, will be your best friends here. On panels, a Golden Taklon filbert or cat’s tongue can help you achieve very smooth strokes without visible scratch marks. For oil, pairing thinned paint with a soft synthetic makes glazing and subtle blends much easier.
If you want visible brush marks and texture
Once you are ready to lean into texture, you can add some firmer brushes that leave more pronounced strokes. Brights and flats with more stiffness will help your marks stand out on the surface. You can keep your Golden Taklon set for smoother work and bring in a few firmer options just for those textured passages.
Pay attention to what frustrates you.
If your edges are always fuzzy, you may need a brush with more snap or a sharper point. If your strokes feel scratchy, you may be using a brush that is too firm for your surface or for how thin you like your paint.
A simple next step
If you want an easy starting point, explore Trekell’s three and five piece minimal sets and then build around them with a short handle Golden Taklon brush or two that fits your main medium and style.
From there, you can add, remove, or swap shapes as you notice which brushes you reach for constantly and which ones stay clean in the jar. That way, every new brush you buy has a clear job in your painting process.
