I purchased several thousand of those full sized yellow envelopes. In each I am going to put my Color Flyer. Then I am going to add a copy of my Mission statement, services performed, and what sets me apart statements. Then I am going to throw in a few pens, magnets and business cards. What I throw in will depend on the neighbor i am releasing them to. For instance, higher end neighbor hoods will recieve more junk in the envelope. Anyways let me know what you think of this material.
