Do natural hair or synthetic brushes perform better for watercolor techniques?

Natural Hair Brushes (Kolinsky Sable, Squirrel, Goat)

• Water retention (holds more pigment/water for seamless washes)

• Snap/spring (bristles return to point for precise control)

• Delicate blending (creates smoother gradients)

• Professional results (favored by master watercolorists)

⚠️ Drawbacks:

• Expensive (top Kolinsky brushes can cost $100+)

• Ethical concerns (animal-sourced bristles)

• Require meticulous care

Synthetic Brushes (Nylon/Polyester Blends)

• Affordability (good quality for 1/3 the price of natural hair)

• Durability (withstands harsh treatment better)

• Consistency (no batch variations like natural hair)

• Vegan-friendly (cruelty-free options)

⚠️ Drawbacks:

• Less water-holding capacity (may require more reloading)

• Can lack "snap" in larger sizes

• May not last as long as premium natural brushes

Surprising Hybrid Option:

Modern synthetic-sable blends now rival natural hair performance at mid-range prices.

When to Choose Which:

• Natural: For professional work, large washes, or if you value traditional techniques

• Synthetic: Beginners, travel kits, or if you prefer vegan materials

• Hybrid: Best balance for serious hobbyists

Pro Tip: A high-quality round #6 in either type will reveal more differences than smaller/larger brushes. Test both to feel how they release water onto paper.
