villabarnes: Gesso Magic Gesso is a thick substance, somewhere between plaster and paint, artist use it to prep their canvases. Apply a thick coat of gesso right out of the container, before it was completely dry, go over it with a dry brush, to smooth it out a bit. You don't have to use a different brush, just take a dry rag and remove most of the Gesso from the brush you are using.
