I've used this process with great success. It's known by many names- lasagna gardening, sheet composting, interbay mulch...
The process is the same- cardboard or thick newspaper, then layers of organic material, whatever you have- kitchen scraps, coffee grounds, straw, grass clippings, fall leaves, hay, weeds, dead flowers, used potting soil. The possibilities are endless.
I think the only difference in sheet composting or lasagna gardening and interbay mulch is that the interbay mulch is covered with burlap. (This started in Seattle. They have all that coffee! and therefore free big burlap sacks). Lacking the burlap, I have used other natural material- cotton sheets. Worked well. The fabric on top of the hump helps keep things moist and dark, encourages bacterial and fungal growth to aid breakdown.
An important step is moistening as you build the hump. It can be really tough to get it moist after you build a hump of a foot or more of stuff. Keep it moist. Doesn't need wet, just moist. When it all drys completely, breakdown stops, so you want to keep it moist. It breaks down much better/faster.
