Canvas
Splined canvas, stretched canvas and canvas boards

Splined canvases differ from traditional side-stapled canvas in that canvas is attached with a spline at the rear of the frame. This allows the artist to incorporate painted edges into the artwork itself without staples at the sides, and the artwork can be displayed without a frame. Splined canvas can be restretched by adjusting the spline.

Stapled canvases stay stretched tighter over a longer period of time, but are more difficult to re-stretch when the need arises.

Canvas boards are made of canvas stretched over and glued to a cardboard backing, and sealed on the backside. The canvas is typically linen primed for a certain type of paint. They are primarily used by artists for quick studies.
