Answer : There are many different ways to learn interior design, but taking some formal courses is a great way to start. After 12th grade, you can enroll in an Associate's or Bachelor's degree program at a vocational school, community college, or four-year university. Or, you could choose to take some individual courses at a local design school. Many professional interior designers also recommend getting some experience by interning with a professional designer. No matter which route you choose, taking the time to learn about interior design will help you develop the skills and knowledge needed to create beautiful and functional spaces.
