I like the paperweight idea. Not for a church, but we have done something similar for the young ladies of our auxiliary. If they join as 'junior' members, when they graduate from high school, as part of their recognition from our organization (at least when I was prez) was an engraved silver star paperweight. I've gotten them from 'Things Remembered' both in-store and online. That store has many choices for reasonably-priced, engraved items. And the quality is very nice.
