"Quotation Sandwiches"

On an article about properly using quotations, Graff (2011) inquires "To adequately frame a quotation, you need to insert it into what we like to call a "quotation sandwich,"  with the statement introducing it serving as the top slice of bread and the explanation following it as the bottom slice"(Graff 46). Irony aside, I believe the usage of quotation sandwiches is crucial to any solid quotation, as it makes sure it covers not only the follow-up, but also the reasoning following the quotation.
