Featured How-to Guides

A guide to: Watercolour Floral

“My name is Malgorzata Zdanio, I live and work in Belgium, and I’m a self-taught artist. My style and practice are influenced and inspired by nature, so for me, the translucency, luminosity and pastel qualities of watercolours help bring that inspiration to life. For my floral tutorial I’ve used Winsor & Newton Cotman Watercolours and brushes.”
