Creating decorative bedroom ideas like a transformation process of ideas into the canvas. The first step is choosing the suitable materials for the media. Acrylic paint is the best option for the wall medium. The next step is about the painting itself. If we want to paint the wall mural art in realist and naturalist based on photographic objects samples, then it can use the simple technique with a grid method (this is very commonly used in mapping techniques) or transfering directly with projector. Both techniques are very easy, simple and effective way to reproduce the paintings, especially if supported by a strong talent in fine art.
