Hi! I’m no Mr. Kate, BUT I’m currently in my final year of an Interior Decorating program. It’s a little different from interior design, but there are a lot of similarities. It’s hard to narrow down all the things you learn, but just be prepared for a lot of hand-drawing, as far as I know. It becomes one of the main things you do during the whole program. You will get into different computer programs too. It’s a much bigger work load than you would think, but it’s a lot of fun. Good luck on your future endeavours!
