This year I helped the boys make pomander balls with oranges and cloves. I do this at school with my second graders during our Christmas Around the World unit. This tradition comes from Great Britian. They make the house smell so nice and they are pretty to look at too. If they lose their scent, you can put them in the sun for a few hours or in the oven for an hour at 110'. I remember my Mom doing this as a child with oranges and lemons, too.
