Who: Engage the youth group, or the fitness crowd
What: Print your church name, address phone number, and website on transparent labels. Stick your label on Stillspeaking doorhangers and let your energetic walkers go! Put a doorhanger on every door on the street / block / neighborhood.
When: Anytime, but especially before a holiday or big event at your church.
Where: All over the street, or the block, or the neighborhood.
Why: Besides sharing the message - "Never place a period where God has placed a comma," - the visual impact of all those hangers is strong. It'll help people notice and remember your invitation.
