Create a "Walk-up Cross" in a prominent location
On Good Friday in some churches, it's traditional for members to nail a message of repentance and forgiveness to a wooden cross.
The same idea can be transformed into an "outdoor reflection" spot that invites the community to participate. Different Sunday School classes could help create or staff the cross during Holy Week. Here are some photos and suggestions along those lines.
You might place a Bible verse and question at the foot of the cross for contemplation, as well as some inviting chairs and benches at a VISIBLE sign that people are invited to come sit.
You could invite a class or family or two to organize and build it, and others to tend to it.
You could create it as a "vigil" where the community could see someone sitting at the cross every evening of Holy Week, and have a sign with a pithy welcome saying.
On Easter Sunday, ADD FLOWERS to the cross and leave on display throughout the week.
Invite people to leave messages by having a basket with small sheets of plastic cloth available (such as cut from an inexpensive plastic table cloth), and a sharpie marker attached by string to the basket.
