Art From Sandwiches

The verb to sandwich has the meaning to position anything between two other things of a different character, or to place different elements alternately, and the noun sandwich has related meanings derived from this more general definition. For example, an ice cream sandwich consists of a layer of ice cream between two layers of cake or cookie. Similarly, Oreos and Custard Creams are described as sandwich cookies because they consist of a soft filling between layers of cookie.
The word "butty" is often used in Northern areas of the United Kingdom as a synonym for "sandwich," particularly in the name of certain kinds of sandwiches such as a chip butty, bacon butty, or sausage butty. "Sarnie" is a similar colloquialism.
