Saunders Waterford is an exquisite English watercolour paper, traditionally made on a cylinder mould machine. This is the superior quality paper made at St.Cuthberts Mill and comes with the Royal Watercolour Society's endorsement. Made using 100% cotton, the highest quality papermaking material, to archival standards. Each sheet is buffered with calcium carbonite to help defend finished pieces of work from discolouration caused by acids present in pollution. The Saunders paper has a creamy white colour and its attractive surface is created using natural woollen felts that give a distinctive random texture. The surface is coated in gelatine making it strong and resilient to scrubbing and other rough treatments without the surface tearing. Why use a block? Using a block means you do not need to soak and stretch the paper. Glued on all four sides, the paper remains stretched and cockle (buckle) free. Especially useful for painting on location.
