For acrylics, synthetic brushes are usually the best option because they’re durable, flexible, and hold their shape even with frequent use. Look for soft, high-quality nylon or taklon bristles, which allow smooth strokes and precise control. Flat brushes are perfect for covering large areas and creating sharp edges, while round brushes help with details, outlines, and fine lines. Filbert brushes rounded at the tip are great for blending and creating soft, natural transitions. No matter the shape, investing in good-quality brushes makes your colors apply more evenly and gives your artwork a cleaner, more professional finish.
