Over here in the UK, I saw a beautiful pine cone garland for sale at one of our expensive department stores. I was mega expensive, but on close inspection all the cones were wired together with fine garden wire. I would love to make one to drape down my stair case for next Christmas. My friend is collecting the fallen cones from her tree. I have found that you need to be careful to make sure you dry them out carefully as lots of small insects seem to make them their home and you don't want them invading the house!
