Hey, guys! Well, tonight I have an assignment where I had to look for a quality source that discusses the elements and principles of Interior Design. What I found when researching is a page these two girls made on Houzz for their own assignment. While reading and looking through their pictures, I was impressed with the amount of details that they gave in order to describe the elements and principles. Especially because they went into subcategories with each element and principle. I hope it interests you as well!

Here's the link to their Houzz page:
