I made one of these several years ago, and they are adorable and functional.
Small pine cones/Potpourri/Christmas tree lights/Large mouth jar or Ivy bowl/Lace doily/ribbon/scissors
Place the pine cones and potpourri in the jar about 3/4 the way full. Gently tuck a small string of Christmas lights into the jar. Using a pencil or chopstick move the lights around until they are evenly spaced in the jar. Make sure you have enough of the light string hanging out so it can be easily plugged in. Once the lights are in place, fill the jar the rest of the way with the potpourri.
Then place your lace doily on top and tie a ribbon around to secure. Once plugged in the scent is wonderful. This makes a wonderful gift.
