Explore a unique aquious media with Gouache. It may have a difficult name (we aren't strangers to that here at Guiry's), but gouache is one of the most fun and vesitile media out there. It is a perfect graduating step for a traditional watercolorist, as it is more opaque than watercolor but still behaves in much the same way. Don't be put off by fear of the unknown and try something new if you've never tested Gouache before.
Savoir Faire is certainly a brand you can trust to produce high quality, professional products that are still easy enough to use for intermediate or beginning artists.
