These techniques allow homeowners and designers to achieve a luxurious look without the cost and weight of real materials. Common methods include sponging, rag rolling, and stippling, each creating unique textures and effects. These finishes can be applied to walls, furniture, and even ceilings, enhancing the aesthetic appeal of a space. Faux finishes are popular in interior design because they offer versatility and creativity, allowing for personalized styles that can complement various decor themes.
