One of my friends on the Canadian garden trips was a master at quickly creating the most beautiful tableaus from bark, moss, leaves and stones. This is one of her centerpieces, which changed on an almost daily basis.
pinecone ball - At the top I added a ribbon loop then tied a ribbon bow to it. Use less delicate pinecones and hot glue them to styrofoam ball. In between you can add juniper berries, rosehips, all spice berries. I have sold a ton of these! Wonderful. Mine were also scented by sprinkling scented oils on them.
