Hand sketches play a vital role in the creative process of interior design. They provide a tangible outlet for designers to bring their ideas to life and communicate concepts with clients and team members. Through hand sketches, designers can quickly capture their vision, explore different possibilities, and iterate on designs efficiently. This traditional method allows for a sense of artistic expression and personal touch that may not be fully achieved through digital means. Additionally, hand sketches enable designers to brainstorm on the spot, without the need for complex software or technology, making it a versatile and essential skill in the field of interior design.
