I liked the idea of sailing two pirate ships sail through the front of our church doors after battling out front. Here is the result.
PS Since this is instructables here are the Instructions
Write down an idea
You open with a view of the front of the church
The words VBS fade up
Two pirate ships float in from opposite ends of the courtyard full of pirate kids
They mock fight
They sail through the front doors of the church
The words Welcome Pirates fade up
Gather a group of kids, add swords and get them to pose.
Keep doing this 30 times and then persuade son to assemble footage in imovie.
