Impress Ons by Creative Imaginations can be rubbed onto wood, paper, canvas and various other surfaces. These are a higher quality than your traditional rub-on product which ensures that with the right pressure you can get right into the grooves of your canvas. They make beautiful background touches and add an element of class to your painting. I will quite often place them onto canvas and do a light wash of acrylic over them to soften them into the background.
