If you love the simplicity and portability of watercolor but are frustrated by its limitations, coming home to gouache may be like finding a new best friend. Because gouache dries quickly, it’s entirely possible to complete a finished painting in a single session if you wish, depending on size. But even after a painting is days, weeks, or months old, it is still possible to go back in and rework a finished piece, change it, or add to it. Gouache is portable and lightweight for travel and requires only a few colors, brushes, and some paper to get started. You can always add to them later as your knowledge and preferences grow.
