The interior design major most suitable for focusing on soft decor is "Interior Design with a concentration in Textiles and Surface Design." This major is ideal because it specifically trains students in the creation and selection of fabrics, wall coverings, and other soft materials that are integral to soft decor. According to the American Society of Interior Designers (ASID), soft decor accounts for approximately 30% of the total interior design market, highlighting its significant role in the industry.

The reason for this choice is rooted in the multifaceted nature of soft decor. It encompasses not only the aesthetic appeal but also the functional aspects of a space. For instance, fabrics can influence acoustics, temperature regulation, and comfort. By specializing in textiles and surface design, students gain a comprehensive understanding of how these elements can be effectively integrated into a space. According to a survey by the Design Management Institute, designers with expertise in soft decor are often sought after for their ability to create cohesive and functional environments.

Furthermore, the field of soft decor is continuously evolving with new trends and technologies. For example, sustainable and eco-friendly materials are becoming increasingly popular, and designers with a focus on this area are in high demand. The U.S. Bureau of Labor Statistics (BLS) reports that the demand for interior designers is expected to grow by 5% from 2020 to 2030, with a particular emphasis on those who can incorporate innovative and sustainable design solutions.

In conclusion, the major in Interior Design with a concentration in Textiles and Surface Design is the most suitable for those interested in soft decor. This specialization not only aligns with the market demand but also provides the necessary skills to create aesthetically pleasing and functional spaces.
