Summer holiday begins with packing all the needed stuff in the suitcases. This happened the same way in old times also, but suitcases looked a bit different. They had no wheels, pull-out handles and combination locks. They were frequently made of leather/faux-leather with propping only in their frames. Box-like, inflexible-sided versions were popular too, which looked like very big briefcases. Quality pieces of old times often served a lifetime. They were even inherited through generations laying in attics or used as storages. In lucky case they had stickers of the visited towns on their sides. If we would like to keep these old pieces but use them also, give them a new life by transforming them to our needs.
Separate the two equal part of the suitcase at the hinges. Make a wooden brace frame created by a carpenter (if that is a flexible-sided suitcase, it needs a brace there too). Place two shelves in it, so that a computer can be fitted in. The ventilation and attaching cables are guaranteed because it is open in the front and the back also. Fix four small legs on the bottom.  Leave the original handle, locks and other parts on it, these are great decorating elements. It will look good placed beside the desk in a classic or even in an industrial interior.
Our pets deserve comfortable lairs, but those in shops are quite expensive. The old suitcase can be good for this purpose also with a little fantasy. Open the cover in right angle. Fix it in this position on both sides with braces. Drill four holes on the bottom for screwing the legs. Upholster a custom-cut foam or a big cushion with the desired (washable) fabric. Put it in the lower part of the suitcase, but it should cover the screws of the legs. We can pad the upper part too but if the lining remains visible, it will look very good also. There will be enough space even for our pet’s toys. This is a stylish lair for dogs and cats.
Suitcases can get a new life as wall shelves also. Cut into two parts lengthwise the closed, inflexible-sided suitcase. This way handle will be on one side, the hinges on the other. Fix it on the wall by a pre-drilled console, but the console should be hidden by it. Another solution: drill the suitcase on the wall uprightly. This way the wall cabinet has a sidelong opening „door” that can serve as a mini bar or a medicine cabinet.
Pile up several suitcases (if they are not inflexible-sided, they should be filled with e.g. polystyrene bricks). Reaching the desired height it will be a perfect night table. We can make a night table from one piece only if we fix long legs to the laid suitcase. The inflexible-sided variation is a much more practical choice for this.
Of course, antique suitcases will be showy using them as „only” storage boxes. Ask for help of an interior designer for more ideas.
