Collage is an art technique that is created by attaching or gluing different materials such as papers, photographs, magazine cutouts, etc. to a surface. The finished effect is created by adding many overlapping layers and images to your project. You can then add paints, glitters, trims and more on top of the papers and photographs. Our Aleene's Collage Pauge Instant Decoupage is available in both glossy and matte finishes.
