Weave
If a canvas just has a weight and not a number, it’s a single fill duck. Single fill refers to the way it is woven.
The warp yarns run vertically and the weft yarn is woven between them, horizontally. Single fill ducks just have 1 weft yarn and double fill numbered ducks have 2, making them stronger and stiffer.
Natural Canvas
Most canvas is left unbleached and undyed. It has a natural color and may have dark specs, which give natural canvas a characteristic rustic look.
Dyed Canvas
Dyed Canvas comes in white and a variety of other colors from muted to bright.
Primed Canvas
You can also get primed canvas, which is natural canvas coated with acrylic gesso on one side. It is commonly used for painting on because it won’t absorb the paint like natural canvas will.
