What are the best surfaces for acrylic painting?

Acrylics can be used on a large variety of supports, including canvas, paper, wood, degreased leather, brickwork, or anything which is neither greasy nor too glossy. Professionals and those painters using an oil technique favour canvas whilst paper is used by those working in a watercolour style. Galeria Acrylic Pads are also popular for sketching or outdoor work.

Cotton or linen canvas for acrylic painting? 

You can use either cotton or linen, but as acrylic paint remains flexible when it’s dried, the potential for cracking if you choose cotton is not so great as with oils.
