When shopping for discount art, don't be afraid to mix and match colors and themes. The art in your home should reflect your many tastes. All too often, people will only buy bargain art prints by one artist, or with one particular color scheme and although this may match perfectly, its not necessarily reflective of you as an individual.
If you aren't comfortable with this method of decorating, consider shopping online by "theme" or by "subject." For instance, the works of Kandinsky can work beautifully with the work of Lee Crew or with Rex Ray. Stretch yourself when you're shopping for bargain art - there is no reason not to!
