To launch our first I-3 gathering. We built a heart set. The set is comprised of 3' x 3' spandex panels covered with a black paper mask. These panels are the same ones we used for Battle of the Bands in 2010. We simply covered them with black craft paper that we pre-cut with hearts.
They worked out amazing for the cheesy cupid skit and were very fitting for worship. Surprisingly, when lit they looked like a reasonable set for any "...of the heart" type sermon. If you are interested below are some of the pictures of how we built this set.
