Don’t keep and display every memento.

Don’t mix-and-match too many styles or themes.

Don’t put items together just because they are all one color. Differences in shades and tones exist within one color family.

Don’t buy paint for an entire room without testing it on a small area first.

Don’t be afraid forego “safe” plastic mini-blinds in favor of more creative window treatments.

Don’t apply a theme, such as sunflowers or ivy, to every single fixture or decor. 

Don’t pair unevenly scaled items, such as an oversized sofa with a single small artwork.

Don’t rely on a single overhead fixture to light a room. Use lamps to add interest and mood.

Don’t put all the furniture against the walls of a room. Create small living areas within a larger space to promote interaction and use the space effectively.

Don’t tackle do-it-yourself projects that require more time, talent and money than you are willing to invest.
