Description
The POTENTATE 13×19 cm Watercolor Sketchbook (PC01) is the landscape-format companion for watercolorists who love panoramic compositions and detailed studies. Built from 100% cotton, acid-free 300gsm paper, this elongated A5+ sketchbook is the go-to choice for architectural sketches, rural scenes, and coastal views across Sri Lanka.
The 13×19 cm format naturally suits wide-angle compositions – streets of Galle, rice paddy fields, temple rooflines, and ocean horizons all fit effortlessly within this proportion. The sturdy spiral-bound hardcover construction keeps the book securely open while you paint, with no page curl or wind interference even outdoors.
Cotton paper performance at this weight is drastically superior to wood-pulp alternatives. You can apply multiple wet layers, scrub and lift without damaging the surface, and expect accurate color and granulation from any quality watercolor paint brand. Built for artists who paint seriously, every day.

This is my go-to sketchbook now. The size is perfect — not too small, not too big. 300gsm cotton paper takes multiple layers without any issues. I’ve filled two of these already!

This is the ideal size for watercolor sketching. Not too small, not too big. 300gsm cotton paper handles multiple layers without any warping. The hardcover keeps everything protected. I’ve gone through three of these already.

My favourite Potentate size. I do botanical studies in this and the cotton paper captures every detail beautifully. Wet lifting works so well on this paper. Highly recommend for anyone doing detailed work.

Good sketchbook. Paper quality is great for the price. I mainly use it for urban sketching and travel painting. Compact enough to carry around. The cold press surface gives a nice texture.

Excellent value for money. 100% cotton paper, 300gsm, hardcover — all in a portable size. I’ve tried cheaper cellulose sketchbooks before and the difference is night and day. Cotton makes advanced techniques actually possible.
