Patterns create visual interest, suggest a flurry of activity, and embody a certain style.
Decorating with an obvious lack of pattern can make a commanding statement in an interior.
One which is strong, clean, bold . . . devoid of visual clutter, frivolity, and busyness.
An interior lacking pattern imbues a sense of serenity and seriousness.
It cleanses the palette. Sharpens the eye. Soothes the soul.
It's a scheme or technique that's not for the faint of heart. Only the fearless should attempt this.
