🌿 What Is Cotton Watercolor Paper?

Cotton watercolor paper is made using 100% cotton fibers, not wood pulp like cheaper alternatives. This results in a more durable, absorbent, and textured paper that can handle water, pigment, and layering beautifully.

Each sheet is usually handmade or mould-made, which means it's crafted with care, not mass-produced. This gives the paper its signature texture, deckle edges (in handmade sheets), and longevity.

🎨 Why Is Cotton Paper Better for Watercolors?

Here’s what makes cotton paper the top choice for watercolor artists:

1. Superior Absorbency

Cotton fibers hold water better, allowing your paint to sit on the surface just long enough to blend and bloom. It doesn't instantly soak through or buckle like wood pulp paper.

2. Controlled Bleeding & Blending

You get that magical watercolor effect—soft edges, gentle gradients, and beautiful blooms—without losing control.

3. Layer-Friendly

You can go back and add multiple layers (aka glazing) without damaging the surface. Great for detailed work and professional pieces.

4. Lifting Techniques Work Better

Need to lighten a section or remove paint? Cotton paper allows gentle scrubbing or blotting without tearing or pilling.

5. Archival Quality

Cotton paper is acid-free and made to last—perfect for selling original artwork, making greeting cards, or creating heirloom pieces.

🔥 FAQs: Cotton Paper for Watercolor

Q: Can beginners use cotton paper, or is it just for professionals?
Absolutely! In fact, beginners often get better results with cotton paper because it’s more forgiving. Paint flows better, and your work looks more vibrant.

Q: Can I use both sides of the paper?
Yes! Both sides are paintable. The texture may vary slightly, so test each side to see which you prefer.

Q: Will it work with other media like ink or gouache?
Yes—especially our 250 GSM paper. It’s versatile enough for watercolor, gouache, ink, pencil, and even light acrylic work.

Definitely. The natural white tone and deckle edges make it perfect for mini artworks, greeting cards, and hand-painted stationery.
