Most of my mixed media art pieces are acrylic paint and paper collage on canvas. I love to incorporate vintage wallpaper into my work too. Sometimes I'll cover the canvas in wallpaper and use that as my base to paint on, other times I will use accents of wallpaper in my art. It really depends on the piece, and the quality and size of the wallpaper. I source authentic vintage wallpaper - not reproduction - so often it can be brittle or fragile.
