Can newspaper be used as a weed barrier before adding mulch/bark? How thick should paper be applied? How thick mulch?

I use about 6 layers of newspaper under my mulch and it works beautifully. Or you can use a single thickness of cardboard if that's available to you. The mulch material should be 3-4 inches thick to keep weeds from sprouting.
