We saved so much money that first year that we actually asked for LESS money for our second year. We spent it, of course, but on starting a children's Fellowship. When a large church writes its own curriculum, Sunday School can cost less money. Thus, a Rotation Sunday School can start to acquire some pretty neat stuff if they write their own. Ok, so we were lucky, maybe.
Some churches DO spend a couple of thousand dollars converting their rooms.
Some had bad rooms to start with. But many other churches spend only hundreds of dollars because they are good at finding things, asking for things, and letting people know what they need. Take theater seats, for example. You see them in many A-V Workshops. Some churches have paid for theirs.
