Here's the new wreath I made last year for our backdoor.
I started with a wire hanger and bent it into a circle.
Then I wrapped the wire with newspaper and taped it around. I took sheets of newspaper and crumpled it into long tubes and then formed around the wire and taped it in place, then I added more until it was thick enough. I then taped all around to smooth it out. I spray painted the wreath white. And now you have a free wreath form.
