The hottest Christmas theme this year is *Peace*. Most likely this influence comes from Barney's 2008 Hippie Holiday theme which celebrated the peace symbol's 50th anniversary. Pottery Barn is a great source for peace themed ornaments and the like. I picked up a little box of 50 sparkly peace symbols from there for $10. They make excellent ties-ons for gifts or little ornaments to add to your tree.
Here is look at Pottery Barn's collection of Peace ornaments, some of which you could easily make yourself. If only I had more time I would make some of the hearts with the embroidered peace symbol...maybe next year.
