Small dining rooms are often just teeny nooks carved out of a bigger space. Try to unify the dining area with the surrounding space. For example, if you have an open kitchen use the same scheme in the dining area with colourful accents to make it stand apart.
Storage really matters: Clever storage units could be a boon both in terms of visual appeal and functionality. For instance, give the illusion of built-in cabinets to make your kitchen look neater and more spacious.
