See the discussion of the STUMP of Jesse which is part of a creative "branches" wreath idea.

See this pastor's discussion of the Stump of Jesse and what it really says to us. Very interesting.

Make a Jesse Tree in a pot with a real branch stuck in a piece of styrofoam and covered with stones

I wonder... instead of hanging ornaments each day on our Jesse Tree, why not put them all on the tree to start with, and PLUCK ONE each day like a fruit and "do" what is written on the back of each ornament. Jesus used the tree image to teach us that we need to produce good fruit. 

For example, on the back of the JACOB ornament, write a "food" to donate or make for someone to help remember that Jacob used food to deceive his father and stole his brothers birthright, and yet, was still part of Jesus' family tree. Making/giving food to help is good fruit.

Kids could decide what "action" should go with each ornament in advance, write them and hang them.

Kids could decorate the pot.
