I would like to know the meaning of "you're working with nature's own quilt".

Any skier can tell you what good snow is, but when you're out shoveling your driveway in the winter, you may feel hard-pressed to find any good words for the white nuisance. Actually, in cold climates, snow is far more useful than even most skiers might imagine. When snow covers the ground, it's an excellent insulator against the colder air above. The snow protects plants and animals that can survive under the snow at temperatures slightly below freezing but would die in the outside air. So if you live in a cold climate, try to remember this winter as you're out shoveling that you're working with nature's own quilt.
