One idea for my engineering projects is a wooden shelf with a built-in cork board and supply organizer. This would allow me to store books, folders, supplies, and more.
The project would look similar to the image above, but a cork board would replace the top shelves, and the bottom right corner would be the supply organizer.
The cork board would cost $6. The wood for the shelf would cost about $18. This project would be both affordable and doable.
