I used gilded walnuts in my Thanksgiving centerpiece, but they make great ornaments with a little ribbon loop glued on top. I bought a bag of walnuts at the grocery store for about $3 dollars and painted them with gold acrylic craft paint I had on hand. You could also use them to embellish gifts. Kids might enjoy painting them as well. They don't shatter when knocked off the tree and are too big to be a choking hazard. Since the paint is non-toxic, I might throw them in the backyard this winter for the squirrels. They'd certainly be able to find them.
