Use a foam brush and acrylic paint to paint the outside edges of the canvases and a little bit onto the front. Let dry.
Use a second foam brush apply a medium, even layer of Mod Podge over the entire front of the canvas. Work quickly.
Smooth the photo onto the canvas that you just coated with Mod Podge. Press firmly and smooth the photo with your hands to remove air bubbles.
Turn the canvas over onto your work surface and smooth from the back as well. Turn back over and let dry.
Use a foam brush to apply long, thin, even coats of Mod Podge to the surface of the photo. The strokes with give the photo a textured appearance. Make sure there are no clumps or thick areas and let dry.
Repeat with the other canvases. Let dry for 24 hours before hanging.
Notes
The photos can be printed on almost any kind of paper for this project, though the less glossy the better. They should be printed laserjet to ensure no bleeding of colors.
