Robinette Boulanger Duvet Covers March 21, 2018 20:10:16
Once you have the duvet insert measurements the measurements of your duvet cover can range from being the same size as the insert to being about two inches larger in both directions. For instance if your queen size insert measures 85" wide by 90" long your duvet cover should be from 85 to 87" wide by 90 to 92" long. Since both insert and cover are made of cloth and flexible these limits can be pushed a little but be sure the item being purchased can be returned before going too far outside of the determined range.
The value of the comforter along with the fact that it is difficult to clean lead to the "invention" of the duvet cover. Similar to the concept of a pillowcase the duvet cover protected the down or silk comforter from body oils and all the other elements that might soil it.
