I used 4X8 sheets of white coroplast hung by black chain to create the reflective surface for the center projector. I also treated the entire room with a breakup pattern in an amber color.
We also did baptism as part of our easter service we have always done it at the lake during the summer and baptize a large number of people. We have started doing them in small numbers. I was against each person sharing their testimony but in the end think we should always do small numbers so they can share. This became a real family moment and people connected on an emotional level to each of the people being baptized.
