Decorate your walls by putting up murals, art or branding designs that represent your brand and provide visual interest to your store. Furniture: Select pieces that are functional, comfortable and match the design of your store. Consider options such as sofas, tables, chairs or display case. The purpose of decoration is to make the space more aesthetically pleasing and functionally useful for the occupants, but this may include consideration of wider contextual issues such as fashion, culture, and so on.
