We did this when we dedicated our new church building 18 months ago. We showed the first building and subsequent buildings, as well as the stages of building our new church. We plan to do this for our 50th anniv. We have old newspaper articles, advertisements, Sunday school promotion fliers, etc., that we will incorporate. We do a slide show each year at our watch night service in New years Eve.
Someone puts the slides in the slide trays chronologically.
The narrator mentions each occasion and the prole involved. It's one of the highlights of watch night. In response to Julie F., We have a big blast for our Harvest Party. We also rent some sort of a blow-up Bounce type game every year as well as have the game booth's. We have a cake walk.
