Breathing new life to a worn-out bookshelf

Two years ago, I assembled a bookshelf using only a Swiss knife (because I didn't know where the proper tools were stored). We never did use it as a bookshelf because we've used it as an open cabinet for clothes. For most of its use (so far), the cabinet had been standing tall. 

But the presence of a baby has made us review the risks posed by the furniture we've got at home. The most obvious of which, for us, was that a lot of our stuff are fall risks in the event of an earthquake. 

Three bookshelves are now lying horizontally on the floor. I decided to use the one assigned to me as a clothes container again with each shelf acting as a partition for clothes (and there won't be too many clothes piles collapsing because of the weight!). The second one is also used in the same way but for Anna's clothes. The third one is assigned to the dining area or the living room; I'm just not sure how it's going to be positioned and what its contents will be.

With just a little imagination, we're able to repurpose our furniture, successfully not adding to our expenses. For me, the next step is to identify clothes that I can't fit into anymore...
