Margaret is known internationally for her pastel painting, teaching and writing. She also paints in oils, acrylic, watercolour for bold, colourful sketching diaries of her travels, gouache to work in with her pastels, and her first love, oil painting, which she first studied and graduated in, from Glasgow School of Art. She promotes and endorses pastels as a serious & worthy medium, as they can be used in dry or wet techniques.
Through teaching and travelling worldwide, her work has become bolder in tone and colour, painting plein-air whenever possible, inspired by many artists she has met along the way. Respected tutor and author of many art books and publications, she tutors worldwide, and appears in art television programmes. She paints landscapes, still life, flowers and undertakes portrait and animal commissions.
