Seminary Mom used lunch sacks to emphasize the importance of the material in 3 Nephi -- truly a spiritual feast. Kids in her class added notecards to their lunch sacks each day during the lesson to add to their feast. It's a great example of how to carry a theme over multiple days for lesson continuity. Below is her description of how it worked.

This theme could be adapted to a number of lesson types, including Family Home Evening and even Sunday lessons or Mutual.
