Third, paint the items all bright color(s)
In a small-sized kitchen and with the very limited space for the dinette, the alcove where your family and you will eat every day, nuance is not less important. The recommendation that I can give you here is that you need to make it look not too crowded. You need to paint all the items bright, brighter than before. Or, you can think about buying some bright furniture items to prevent doing so.
Alternatively, you can also create the dining set on your own or pay some artisan to do so. But, it is sometimes not efficient choice.
Opting to combine some items you’ve bought separately is the most fruitful solution because you can choose the slenderest kind for each item that you want to have, e.g. the table. In practice, you may face unlimited choices like small chairs, long benches, three-legged bar stools, etc.
