I made this wreath out of black roses for Halloween:
I ordered the roses off of e-bay b/c they were much cheaper there than at my local craft store. Then I cut a wreath form out of several pieces of cardboard. I cut the stems off of the roses and hot glued them to the cardboard wreath form. Then I attached an orange ribbon to the top of the wreath and used another piece of orange ribbon to hang it on the door.
