Making the world better, one answer at a time. The word foil in drama means a character or scene that is set up as a contrast to another so that each will stand out vividly.. Hope that helped.
Typically, a comforter is a thick, quilted, fluffy blanket that is used to keep you warm. It is usually filled with synthetic fiber filler which is quilted or stitched to secure the filling and keep it evenly distributed. Unlike a duvet, the comforter only forms one piece of all of your bed linens.
A duvet without a cover. Most comforters do not have a natural filling that is difficult to wash, and so most are made to be put directly into a washing machine. This means the entire comforter must be washed, rather than simply a cover. This is especially true of comforters from bed-in-a-bag sets.
