best use for shredded paper/cardboard?
I have a 3/4 acre lot (house takes up part of it), I compost alot, have 4 piles, and many gardens. I shred just about all paper and cardboard boxes/packaging. So I have a few bags of shredded stuff here. As you know it does not break down quickly. I've used it as part of lasagna garden building, or just to smother lawn in making a new garden. I also have alot of leaves bagged right now. These are both high carbon, right? What is the best use for this shredded paper? Should I mix in compost piles? Should I mulch with it (covered with something more natural?). Maybe the best is to wait for grass clippings and mix with that? What about in fall/winter -- best use? Thanx!
