You could use the cookie cutters to cut a thin layer of clay or polymer clay into the shape of a leaf. Make indentations for the veins, attach a hanger, and then bake the clay according to the directions. Afterwards, spray them with some shiny gold paint (or any other color paint).

Another suggestion would be to gather some real leaves (ones that have dried out) and spray them with your paints. Have fun.

Magnolia leaves are beautiful & just tuck into the branches. Natural, polished with furn. polish or painted gold, silver or white with gltter sprinkled on while paint is wet. I have a swag made six years ago that's looking a bit ragged now, but it made a 600 mile move!
I also use interesting weedseed heads - some painted & glittered, some with only hair spray & some with fake snow.
Try a bunch of stuff with $1. paint & have fun! Suzi
