Why not get some:
Posters to put inside and outside your Church.
Flyers to drop through the neighbours' doors or hand out to raise awareness.
Bookmarks to give away at the end of an event or service.
Banners to put up inside and outside to show your service or event is on or use as an effective backdrop.
Customise any of the above with the wording of your choice.
Screen Graphics to welcome people or to enhance the overall experience.
