The paper has a fine grain that is the same on both sides of each sheet, so a painting can run across the whole open spread. Hahnemühle makes the book in two papers: 100% cotton and cellulose. ## Watercolour Book 100% Cotton specs **30 sheets of 250 g/m² natural-white cotton paper in a black hard cover with a ribbon and an elastic band.** Hahnemühle's German page lists: | Spec | Watercolour Book 100% Cotton, A5 portrait | |---|---| | Item number | 10625352 (GTIN 4011367115975) | | Size | A5, 148 × 210 mm (5.8 × 8.3 in), portrait | | Paper | 100% cotton, 250 g/m² (92 lb), natural white | | Surface | Fine grain, same on both sides; surface-sized | | Sheets | 30 (60 pages) | | Cover | Black hard cover, black ribbon, elastic band | | Archival | Acid-free, age-resistant, vegan | Hahnemühle says the cotton suits every watercolor technique, especially wet-in-wet.

One version is. Hahnemühle sells the Watercolour Book 100% Cotton at 250 g/m² and the original Watercolour Book in 200 g/m² cellulose paper; check the cover before you buy. ### How many pages are in a Hahnemühle Watercolour Book? 30 sheets, or 60 pages, in every size of both the cotton and the original versions. ### Can you paint across both pages? Yes. Hahnemühle says the surface is the same on the front and back of each sheet, so you can carry a painting across the full width of the open book. ### Does the paper buckle with heavy washes? Some buckling is normal in a sketchbook. The 250 g/m² cotton paper is heavier than most sketchbook paper but lighter than a 300 g/m² block glued on four sides. ### Can you use masking fluid in the Watercolour Book? Yes. Hahnemühle says masking pens and tapes come off the cotton paper without residue, and its surface sizing even allows erasing. ### Does the Hahnemühle Watercolour Book come in a square format? Yes, two: 14 × 14 cm and 19.5 × 19.5 cm, in both the cotton and the original versions, alongside A6, A5 and A4 in portrait or landscape. ### Is the Hahnemühle Watercolour Book vegan? Yes. Hahnemühle says all its papers, including both Watercolour Books, are vegan, acid-free and age-resistant. ## Sources - [Hahnemühle (DE): Watercolour Book 100 % Cotton (250 g/m², 30 sheets / 60 pages, formats and item numbers 10625350–10625357; cover, ribbon, elastic; acid-free, vegan)](https://www.hahnemuehle.com/de/kuenstlerpapiere/aquarell/watercolour-books/p/Product/show/328/1291.html) - [Hahnemühle (DE): Watercolour Book (200 g/m², 30 sheets / 60 pages, moisture-repellent cover, formats and item numbers 10628810–10628816)](https://www.hahnemuehle.com/de/kuenstlerpapiere/aquarell/watercolour-books/p/Product/show/328/800.html) - [Hahnemühle (DE): Watercolour Books collection (cotton or cellulose, 200, 250 and 300 g/m²; Deckle Edge, Toned and ZigZag books)](https://www.hahnemuehle.com/de/kuenstlerpapiere/aquarell/watercolour-books.html) - [Amazon US: Hahnemühle 100% Cotton Watercolor Book, 5.83 × 8.27 in, Portrait (10625352; GTIN 4011367115975; ratings and rank read October 23, 2026)](https://www.amazon.com/dp/B09NYB1R1W) - [Amazon US: Hahnemühle Watercolor Book A6, 200 g/m², Landscape (ratings read October 23, 2026)](https://www.amazon.com/dp/B01CD7YXBY)
