Plastic fall leaves (I got mine from Hobby Lobby on a stem and plucked them off)
It's pretty self explanatory from here, you simply tie a little knot around the stem of the leaves and tie another knot around the branch. For the other leaves that are directly on the branch, I dabbed hot glued the stem of the leaf and pressed them onto little nubs or slid them onto small twigs still on the branch. Mine also came with a little acorns so I put those on too! You could hang these guys on a wall, over your bed, or even tie it to yourself if you like it that much. You could also add feathers or whatever else you can think of!
