I just frowned at my cardboard boxes.

I’m aiming to build something similar out of wood soon.
But I also had an idea to build a bookshelf with drawers incorporated, a row of vertical draws on both sides of the shelf and/or one down the middle. Ideally creating book cubbies between the drawers where I could organize related books next to appropriate zettles. Not sure how attached to that idea I am though, seems like something I will like for the moment and find very novel in the future (pun certainly intended).
