Trying to distinguish your home from others is about taking risks and sourcing your furnishings from places other than the obvious big box stores. Adding in carefully thought out antique pieces gives your home visual interest and makes it feel cozy and lived it. Eclectic touches are a great way to experiment with your style and all great designers know this and do this often.
Think in terms of differences to play off of each other by mixing hard and soft textures, square and round shaped pieces and thick and thin sized items. The room will be anchored and yet elevated by the contrast between the antiques and modern items in the room.
