Still, you can easily add texture to your plaster by using the edge of your trowel or almost any kind of tool that can be pressed into plaster. In fact, you can even add minimal amounts of extra stuff (hay, seashells, sand, etc.) to create more texture.
In summary: pick a special room that isn't too large and give this plaster product a try. Special? Well, how about a sewing room, child's room, study, or a home office? Not too large? The home office I am working in right now, which is your basic child-size bedroom, big enough for a twin size bed, has about 400 square feet of wallspace. So, I would be looking at about three 50-pound bags of American Clay.
