I had the wire coat hanger, and the screen mesh on hand , All I had to purchase was the orange plastic table cloth for $1.00 at the Dollar Store . and Boom ‪#‎HalloweenWreath‬
You will need 1 wire coat hanger, 1 54″ plastic table cloth and a few squares of screen mesh, 
Take the coat hanger and un-twist and form your desired shape, I did a circle and taped the ends together, cut table cloth into 3 inch by 3inch strips and loop around the coat hanger and tie into a knot and continue this and as you add strips push each one down until the circle is completely filled in between tie strips of screen mesh, this took me about 2 1/2 hours to complete.
