Cut a sheet of batting with a pair of scissors to cover the ground area. Cut it in an irregular circle, oval or rectangle. Avoid perfectly straight edges, as they will look less realistic.
Remove the outdoor decoration from its spot and lay the batting over the spot. Replace the decoration.
Cut 1/2-inch slits in four exposed corners or sides of the cotton batting. Do not cut through the edge; rather, make a buttonhole-type slit.
Push tent stakes through each of the slits to hold the batting in place. Use a hammer to tap them in if the ground is especially hard.
Sprinkle white glitter over the exposed batting to add a glistening effect to the fake snow.
