We started doing the "giving thanks" around the table last year---like this idea too! Everyone writes, on the stick what they are thankful for. When seated for dinner, the jar is passed around the table & everyone picks a stick to read out loud.
I love popcorn....I could do this with those candle sticks that have a liner between the candle & the outside...or use that round centerpiece bowl....upside down with the inner circle filled with acorns etc. Also use with flowers in place of candle.
