With the increasing amount of incoming stuff in the house as against the obviously inflexible volume of the structure, storage of household items becomes quite a headache. Though there are ways in which a shelf can be extended or an entirely new case can be purchased, there are still many other affordable ways to make space for that extra chunk of goodies. Let us take an example of how you can add more space to house the extra books which cannot find place in your already filled bookcase.
Though it sounds like a crude ‘dorm boy’ styled idea, old milk crates can serve as a good storage space for books, although they would not go very well if you have a theme put up in your room. Another option is to convert your old dressing drawers into extra storage space for books. You can custom paint (or even remodel) them to meet up to your requirements.
