Abstract

A two-piece canvas button comprises a shell, a back, and a piece of artist canvas tightly tucked between the shell and back. The shell provides a sturdy mounting for the artist canvas, on which an artist paints. The back may be a formed back with a frusto-conical margin that cooperates with a frusto-conical wall of the shell to tightly tuck the artist canvas. Alternately, the back may be a flat back, in which case the artist canvas is tightly tucked between the periphery of the flat back and the shell frusto-conical wall. A round canvas button with the flat back may have a flat coplanar flange; the artist canvas is tightly tucked between the flange and the back. A rectangular canvas button has coplanar flanges. Machines for manufacturing the canvas buttons may use either a third press stroke or only two strokes to manufacture the buttons with the coplanar flanges.
