I want this in my dining room! Wooden crates DIY diy-for-my-home Love old crates and this idea for using them. I already hang them as decorative shelves to hold some of the "random artifacts" I've collected(Aedan's term for them)
add wood wallpaper to the kick plates of the stairs. Those rolls are expensive but you would only need one. Not practical with white treads though, it will be stuffed up from black shoe soles in no time.
Line: The book shelf in the room shows the use of line because the book shelf shelves are built against the wall forming a miniature tree. Our eyes are drawn to look at the book shelf tree from bottom to top and outward to the tree/bookshelf branches.
