Since the theme is "Aloha, Cub Scouts" in February 2007 you may want to consider using decorations such as palm trees, mats, low tables, leis, Hawaiian music, pineapples, coconuts, volcanoes, tikis, hula skirts, canoes, surfboards, Hawaiian shirts, reefs, corals, fishnets, water/waves, fish, shells, etc.
The boys should be involved in making banquet decorations. They should be simple and not time consuming. Things boys might make are: centerpieces nutcups placemats name cards Napkin rings corsages boutonnières favors
Other Decoration Suggestions: Helium Balloons, Streamers, Pictures of Pack events, Projects the Cubs have made, "Old" scouting items of the past
