Arnold's unique signature style of painting developed from combining the fluidity and lightness from her years as a watercolorist with the capability of acrylics and oils to be layered. She uses extremely thin washes of paint with many layers of transparent washes in each painting. The light shimmering through the many layers of warm and cool colors, along with the textures makes her complex paintings glow. Arnold says, My paintings end up not only being very subjective, but with images that I can strongly relate. They often mirror my life in a spiritual metaphor. A professional painter for over thirty years, Arnold's work is in many public, corporate and private collections. She has participated in one and two person shows and in numerous juried and invitational exhibitions. Arnold also teaches intuitive painting in several workshops a year for beginners and professional painters.
