Watercolor Brushes - What You Need To Know
If you’ve been painting for a while, you probably know the joy of strolling through an art supply store. So many exciting choices, so much variety!
And then comes the question: What do I actually need? What should I look for?
The classic dilemma of choice...
And yes, this feeling can also arise when selecting the right brush for your botanical painting.
After all, the brush plays a crucial role in the success of your artwork.
It determines how precisely you can work—whether outlining delicate leaf edges, creating smooth gradients, or managing the right amount of water for your painting. The right brush can make all the difference.
In this article, you'll learn which qualities a brush should have for botanical illustrations, what shapes and materials are available, and which brands are particularly popular among artists.
A little guide to help you choose your next brush wisely—saving you both money and frustration!
1. Why Is the Right Brush So Important?
The right watercolor brush greatly influences your painting experience and results. That’s why it’s important to invest in quality.
No, it doesn’t have to be the Ferrari of brushes, especially if you’re just starting out. But the cheapest option might not be the best either, as low-quality brushes tend to fray quickly.
So how do you recognize a good-quality brush?
Here are some key aspects to consider:
Tip: A fine tip allows for precise details, such as leaf veins or flower structures.
Water Retention: A good brush holds water like a sponge—but releases it in a controlled manner, reducing the need for frequent reloading.
Elasticity: The brush should return to its original shape after each stroke without fraying.
Grip: If the brush feels comfortable in your hand, you can paint longer and more effortlessly while maintaining full control.

2. Which Brushes Are Best for Botanical Painting?
There are countless types and shapes of brushes, but some have proven particularly useful for botanical illustrations:
Round Brush: A true all-rounder! Suitable for fine details as well as larger areas.
Wash Brush: Ideal for wetting paper with water or creating smooth gradients.
Eradicator Brush: A kind of “eraser” for watercolor—perfect for correcting uneven edges or lifting color.
Mixing Brush: Special synthetic brushes that hold less water, making them great for mixing colors without soaking them up.
Miniature Brush: Perfect for tiny details, such as stamens or fine leaf veins.
Tip: Start with a good round brush in size 6—you can accomplish a lot with it! You can always expand your collection later.
3. What Types of Brush Hair Are Available?
In recent years, there has been an increasing debate about whether natural hair or synthetic brushes are the better choice—from both an ethical and environmental perspective.
While Kolinsky sable hair is criticized due to concerns about animal welfare, synthetic brushes contain plastics that may contribute to pollution.
It’s important to research the available options and make a personal decision.
Below is an overview of the most common types:
Kolinsky Sable: Extremely fine tip, excellent water retention, durable, higher price
Semi-Synthetic Brushes: A mix of natural and synthetic hair, offering a balance between precision & water absorption
Synthetic Brushes: Vegan, more affordable, often slightly less flexible but still durable
My Favorite: I personally love the Dartana Spin Brush from Da Vinci (Size 6)—a high-quality synthetic brush with a fine tip that has served me well.

4. What Brush Sizes Are Useful?
The best brush size for you depends on several factors, such as whether you paint large-scale or focus on fine details.
You may need both small and larger brushes for different techniques.
That said, certain “core” sizes are widely used in botanical painting:
Size 2 – For fine details
Size 4 – For precise lines and small areas
Size 6 – A versatile all-rounder
Tip: It’s worth experimenting with different sizes to find what works best for you! But as mentioned before, a size 6 brush is an excellent starting point.
5. Which Brands Are Recommended?
There are many excellent brush brands available. Here are a few that are particularly popular among botanical artists:
Billy Showell Brushes: Developed by renowned botanical artist Billy Showell
Winsor & Newton: Series 7, classic high-quality brushes
Rosemary Brushes: Especially loved for botanical painting

Conclusion: Your Brush, Your Art!
Ultimately, choosing the perfect brush depends on your painting style:
Do you use a lot of water, or do you prefer dry techniques?
Do you paint highly detailed works or more loosely?
Do you switch between brushes often, or do you prefer using just one?
The right watercolor brush can significantly enhance your painting experience.
Take the time to experiment with different types and find the one that suits you best.
