Don't skimp on the MARKETING MATERIALS for your business. You should care about them as much as you did your logo design. Professionally designed marketing materials like brochures, newsletters, flyers, post cards, advertisements, etc. extend your brand and showcase what your business is all about. Be sure they make a great, lasting impression!
Brand identity goes way beyond your logo. It's the larger, distinct client experience and "voice" of your content. Instant brand recognition should be your goal by offering consistency across all printed materials, website, social media, etc.
