There are several synonyms for the term 'unstretched canvas' depending on the context in which it is used. In the art world, an 'unprimed canvas' refers to an uncoated canvas, while a 'raw canvas' or 'natural canvas' refers to canvas that has not undergone any process to enhance its color or texture. The term 'loose canvas' may refer to canvas that has not yet been attached to a frame or stretcher bars. Additionally, 'untreated canvas' or 'unprepared canvas' may reference canvas that has not been prepped or primed for painting. Whatever the preferred term, the unaltered quality of the canvas offers artists a blank slate on which to create their artwork.
