Encaustic is an ancient medium that involves painting with wax. Here, it's innovated in more ways than one by Collette Collins Design:
You'll generally find encaustic on a panel as a piece of art, not covering an entire wall as an integral piece of a room's architecture. But here, it's been transformed into a wallcovering for an abstract, large-scale accent of color.
