Gypsum wallboard is versatile and economical but often needs some dressing up. Paint is one option, but this clay-based plaster might also fit the bill. The 100 percent natural product is made from a combination of clays, aggregates, and natural pigments and can be used to create a variety of looks that do not require paint. In addition to being green, the clay naturally controls the indoor climate by absorbing and releasing moisture in response to environmental changes, keeping interiors cool in summer and warm in winter. It's available in three finishes and 30 colors. American Clay, 866.404.1634;
