Hey friends! I am THRILLED with how this latest build turned out! The whole thing cost me $100 to build. That includes hardware. Check out my new DIY Industrial Cart Bookcase! How pretty is she? This piece is all about the hardware. Really you are taking a very basic build and a few boards and turning them into a piece of art by adding some awesome hardware. These corner brackets are a new fav! I found them at Home Depot. They are Simpson Strong-Tie brand. They are only $1.53 piece!
