Big paper, big texture, big drama. The Art Spectrum A3 Rough Cotton Watercolour Pad is made for sweeping landscapes, wild coastlines and stormy skies, where a bold surface and a large sheet work together.

Fifteen sheets of 300gsm, 100% cotton at A3 (297 x 420mm). The pronounced rough texture shows at its best on a big sheet, where granulation and broken colour become part of the composition.

★ Art Shed Staff Tip
Splatter is your friend on a large rough sheet. Load a brush, hold it over the paper and tap the handle against a finger. On rough cotton, the drops sink into the texture and look like spray, pebbles or blossom. Cover areas you want to keep clean with scrap paper.

On a small sheet, rough paper adds charm. On A3 it adds atmosphere. Sweep a big brush across the page and the texture creates broken highlights you could never paint deliberately. Granulating colours settle into the hollows like real sand and stone. This is the paper for paintings that need presence on a wall.

Art Spectrum developed the paper with the Magnani mill in Italy, a mill on the Pescia River with a long tradition of artists' papers. It is cylinder mould made and double sized, and the pads are made in Melbourne.

Why Rough A3 Makes an Impact

  • Presence on the wall. Texture and scale together create real drama.
  • Room for bold technique. Splatter, salt and dry brush need space to work.
  • Built for finished work. Acid free, archival cotton for framing and selling.
  • Plant based sizing. Sized internally with a plant based size, with a synthetic tub size on top.

How to Handle a Big Rough Sheet

Tape the sheet firmly to a board on all four sides. Mix far more paint than you expect, because rough texture drinks it. Work from big shapes to small, using a large flat or mop for skies and water, and save the darkest accents for the very end.

To build a landscape kit, add a couple of big brushes from our watercolour brushes and a few granulating colours from our watercolour paints.

Questions About the Art Spectrum A3 Rough Cotton Watercolour Pad

Is rough paper good for large landscape paintings?

Yes, it is ideal. At A3 the texture adds atmosphere to skies, water and land, and it suits loose, confident brushwork. Many landscape painters choose rough paper for finished work.

Do I need to tape down A3 rough paper?

We recommend it. Taping all four edges to a rigid board keeps the sheet flat while wet washes dry and gives a crisp border. Gummed tape gives the firmest hold for very wet work.

Which watercolour paints granulate on rough paper?

Many classic pigments granulate, including ultramarine blue, cobalt blue, burnt sienna and a range of earth colours. Rough paper makes the speckled effect much more visible.

How do I do the splatter technique?

Load a brush with fluid paint, hold it over the sheet and tap the handle. Mask any areas you want to protect. On rough paper, splatter sinks into the texture and looks natural.

Is this paper archival enough to sell or exhibit?

Yes. It is acid free, museum grade archival, chlorine free and contains no optical brighteners, so finished work stays true over time.

Is Art Spectrum cotton paper vegan friendly?

Art Spectrum describes the paper as made with a vegan friendly process. It uses a plant based internal size rather than traditional animal gelatine.
