Watercolour paper buying guide (UK): cotton, weight, and finish
The hub’s short watercolour note promises paper you will not outgrow in six months; here is the longer purchasing framework for East Midlands watercolourists, plein-air groups, and anyone comparing student pads to exhibition sheets.
Cotton rag versus cellulose blends
100% cotton handles lifting, scrubbing, and repeated washes more honestly than wood-pulp student stock. If your work sells, default to cotton for finals; keep blends for travel journals where abrasion and rain are likely.
Weight, buckling, and stretching
Heavier GSM resists buckling when you flood washes; lighter sheets suit sketchbooks if you pre-wet and tape. Blocks remove some warp anxiety for field work en route to garden fairs. Practice stretching on boards before committing to large commissions.
Hot press, cold press, rough
Hot press favours detail and illustration-style edges; cold press is the everyday default; rough rewards granulating pigments and expressive foliage. Grain changes how pigments read—test new tubes on the finish you actually paint on.
Brushes and paper are a single system
Coarse grain dulls cheap synthetics faster; invest in the brush set in our brushes guide when you upgrade paper. Light matters too—evaluate washes under high CRI lamps.
