Yesterday's news is today's mulch

I found this website which has an interesting way of starting a garden. Here's the link: Mother Earth News.  This is not the way we've ever done it, but it sounds reasonable and would be a great use for yesterdays' newspapers. It calls for using wet newspapers as mulch, several pages thick.
Other mulch ideas: Our neighbors used seaweed from the lake. We always use grass clippings and leaves. When we're waiting to plant in an area, we put down a couple layers of black plastic, when we're feeling smart.  I think I'll try the newspaper on our waterfall garden project that we put on hold until we can afford to finish.
