Pro Watercolour Synthetic Round #12
This Professional Watercolour Synthetic Round #12 is the workhorse I reach for when I want range. The belly holds a fair load for mid to large washes. The tip is tight and snaps back fast, which helps with clean edges and dry-brush marks. The handle feels balanced for short handle control, and the nickel ferrule is firm and rust-resistant.
In hand, it performs like a hybrid of sable and nylon. It lacks the extreme water-holding of top-tier sable, but it comes close for a synthetic. The hair blend feels like high-grade PBT with fine tapered tips, which helps with smooth paint flow. For a #12, it carries enough color to paint a sky wash, then switch to a fine twig with a light wrist turn.
Pros:
- Sharp point for line work and detail
- Good water load for a synthetic round
- Fast snap for crisp edges and control
- Durable ferrule and finish that resist wear
- Cruelty-free option that rivals sable feel
Cons:
- Less water capacity than real sable
- Price is higher than entry-level synthetics
- May feel stiff for very loose wash painters
My Recommendation
If you want one brush that can do a bit of everything, this #12 round stands out in my Winsor & Newton synthetic brush review. It is great for hobbyists who paint often and want a premium synthetic that lasts. It also suits pros who prefer a green choice without losing control. It shines in sketchbooks and studio sheets alike.
| Best for | Why |
|---|---|
| All-around watercolor work | Strong point, good belly, fast snap |
| Urban sketching | Switches from washes to detail in seconds |
| Artists avoiding natural hair | Cruelty-free with near-sable control |
Cotman Short Handle 4‑Brush Set
The Cotman Short Handle set gives you three rounds (1, 4, 6) and a 3/8″ one-stroke flat. It is a smart starter or travel kit. The rounds handle line, lettering, and small shapes. The flat gives quick edge control for windows, shadows, and block-ins.
As a budget-friendly pick, this set punches above its price. The hair blend is springy and keeps a fair point. The set works well with pans or small wells, which suits sketchers and students. In my Winsor & Newton synthetic brush review, I find this set ideal for practice, class work, and light plein air.
Pros:
- Great value for four useful sizes
- Good point retention on rounds
- Flat brush handles clean edges and washes
- Comfortable short handles for desk work
- Easy to clean and resilient to rough use
Cons:
- Lower water capacity than pro lines
- Tips can splay if abused or stored wet
- Not ideal for very large washes
My Recommendation
This set is best for beginners, casual sketchers, and gift buyers. You get the key shapes to learn core strokes without a big spend. If you are building a first kit, start here and add a larger round or quill later. In this Winsor & Newton synthetic brush review, it earns a top “budget pick” tag.
| Best for | Why |
|---|---|
| Beginners and students | Four essential sizes at a low price |
| Travel and sketchbooks | Short handles and quick cleaning |
| Mixed technique practice | Rounds for detail, flat for washes |
Cotman Series 111 Round #8
The Series 111 #8 is the “goldilocks” round for everyday pages. It is not too big and not too small. The belly holds enough water for small to mid washes. The point lands crisp lines for branches, lashes, or script.
It has more spring than the pro synthetic range, so it feels snappy. That helps newer painters learn pressure control and lift. It also keeps its shape if you rinse and reshape after use. In my Winsor & Newton synthetic brush review tests, it did clean lettering and tight hatching with ease.
Pros:
- All-purpose size for daily sketches
- Strong spring helps with line control
- Holds a neat point if cared for
- Budget-friendly for a single propped round
- Short handle is great at the desk
Cons:
- Less water-holding than pro synthetic #12
- Can feel firm for very soft blends
- Not suited to very large washes
My Recommendation
If you want a single, low-risk round to learn with, pick the Series 111 #8. It builds good habits for point control and wash timing. It fills most pages without swapping brushes. In this Winsor & Newton synthetic brush review, it is my “best single starter brush.”
| Best for | Why |
|---|---|
| Daily sketching | Versatile size for lines and washes |
| Lettering practice | Snappy point and good control |
| Budget-conscious buyers | Low cost with solid performance |
Pro Watercolour Synthetic Quill Medium
The Professional Synthetic Quill Medium is a wash beast. The bulb holds a big drink of water and pigment. It lays smooth skies and clean gradients. The tip comes to a neat point for reeds, rigging, and leaf veins.
Compared to natural quills, it gives you more snap and less mush. That means better edge control, at the cost of a little water-holding. The synthetic blend resists flare if you avoid hot water. In my Winsor & Newton synthetic brush review, this quill made quick work of backgrounds and broad, expressive marks.
Pros:
- High water capacity for fast washes
- Responsive point for a quill style
- Great for loose, expressive work
- Durable synthetic hair reduces shedding
- Comfortable balance for long sessions
Cons:
- Still less thirsty than natural sable quills
- Large belly can overwhelm small sketchbooks
- Higher price than Cotman quills (if compared)
My Recommendation
Choose the Medium Quill if you love big, flowing washes and bold shapes. It shines in landscapes, florals, and abstract studies. You can switch from a sky blend to twig lines without swapping tools. In this Winsor & Newton synthetic brush review, it is my “best wash brush.”
| Best for | Why |
|---|---|
| Large washes | Big belly holds more paint and water |
| Expressive mark-making | Snappy synthetic quill point |
| Landscape painters | Fast sky and ground coverage |
Cotman Series 111 Round #2
The Series 111 #2 is a detail specialist. It paints lashes, rigging lines, tiny letters, and sharp leaves. The small belly holds enough paint for short strokes. The spring gives quick rebounds for flicks and hatches.
It is not meant for washes. It is the brush you grab for the last 10% of a page. When you need control on the smallest marks, it delivers. In my Winsor & Newton synthetic brush review results, it stayed true to point after months of fine work.
Pros:
- Precise point for fine detail
- Snappy spring aids micro control
- Low cost and easy to replace
- Short handle fits tight desk setups
- Good for ink and gouache too
Cons:
- Very low water capacity
- Not suited for washes or large areas
- Tip can bend if pressed too hard
My Recommendation
Get the #2 if you crave crisp, hairline detail. It pairs well with a #8 or #12 for a two-brush kit. It is a smart add to any travel roll. Within this Winsor & Newton synthetic brush review, it is my “best detail brush.”
| Best for | Why |
|---|---|
| Fine detail and line work | Very sharp, controlled point |
| Miniatures and botanicals | Short, precise strokes with clean edges |
| Mixed media accents | Works with ink and gouache highlights |
