Everyone has already a problem with storing and the lack of storage. If this problem becomes permanent and has a negative effect on everyday life, it’s worth finally to do something for solving it.
First of all: tidy up! Although this is a cliché, but very true. Put everything to its place or at least to the place where it belongs if there would be enough space. Then spend some evenings or a weekend for selecting. Throw away or donate all the things which aren’t needed anymore: old bills, unused clothes for years, broken toys, piled-up plastic bags etc. If this is all what is done, we can be surprised how much space will get free in the house or flat! There will be empty drawers and shelves.
Then we can search for further storages. These help for gathering the things belonging to each other. However, regardless to the original function, almost everything can be a showy storage bin which even hasn’t to be hidden in a wardrobe. For example, the family photos waiting for selecting can be stored in a hat box. A mug can be a penholder, make-up cotton wool can be placed in a prettier jar, spare bathroom toiletries in a pot, sewing tools in an old cookie box, screws/nails in an herb glass with lid and so on. All of them can be even decorated fitting for the style. In the case of closed and similar boxes, it is practical to label them for knowing their content without opening.
If we have good handcraft, we can make a nice storage from a shoe box or a wooden box purchasable in a hobby shop with some paint and wrapping paper. If not, several fancy-boxes and special bins can be bought in various sizes, shapes and colors.  An additional bin can be put in the drawers for small objects, for example which originally was made for ties or teabags. It’s easier to store the things of kids this way also and habituate them for tiding and order.
There can be a bigger problem: for example lack of cabinets or if more people live in a small place. In this case, ask for help of an interior designer, who design the custom-made storage cabinets, rearrange the space for the better use and customize the rooms fitting for the real functions and the needs of those who live there.
