Here is where I got my information from and learned how to roll the bags that go in the container.
You need Mod Podge, a foam brush, and paper or fabric to cover your container.
Cover you container with Mod Podge. Carefully lay the paper on and smooth out the wrinkles as best as possible. Cover the paper with Mod Podge. Let dry and repeat several times. I put 4 coats off matte finish Mod Podge on mine.
