I agree with Neil and Amy! I volunteer with no need to be recognized in church or via a gift.
My church though insists they give me something and for several years, each spring, it's been a beautiful annual flowering hanging basket. I hang it from our front porch where I see it ever time I come and go.
Very nice, but if they were to ever ask me what would be most meaningful to me I would share my Sunday School wish list, and they could simply pick any one item to donate to the Sunday School.
Be it a video, storybook, story table-game-drama prop, etc. would have me dancing in the church hallways and it would be a gift that would keep on giving over the years!
