Adding pattern to furniture is part of creating interesting perspective drawings of interior spaces. When selecting patterns, plan to choose a variety of them such as a curvilinear, a geometric, a small pattern and a large pattern. I first practice drawing the fabric patterns in a small square to see how they will look before using them in a rendering. The image above show the actual patterns and how they were rendered. The quick sketch below shows the variety of patterns that were drawn on the pillows.
