Use branches for wreaths.
Use branches for sprays, centerpieces. Could also use them to make cemetery arrangements. If you have window boxes you could put them in there with pine cones-good for all winter.
Make a wreath for your fireplace or front door.
Instead of spending money trying to transform it, I would suggest that you donate it to a kindergarten or elementary school.
Children will enjoy decorating it, regardless of how old it is.
They will naturally give it new life.
