Cute concept... could get dozens of small jars and tea lights in bulk, use as seating cards (which double as favors!) and at some point have everyone light them, turn out the lights... use as a metaphor for the Gospel of love.
Mason Jar Paint Storage - I do have a lot of mostly empty paint cans that are probably just drying out. I should move them into small jars and label them as to where I used that color or shade. (a little more detail available at link)
