Trim the paper down to fit the canvases, so a little bit of color will show around the edge. Use the ruler and craft knife to size the paper to approximately 11.5". Set aside.
Paint the edges of the canvases with coordinating paint colors. Give several coats and allow to dry.
Pour a bit of Mod Podge into the center of the canvas and spread out a medium layer. Work quickly and get the corners well.
Lay the paper down and smooth thoroughly - wipe away any Mod Podge that comes out the edges.
Canvas is flexible, so turn the canvas over and smooth on the backside as well. Allow to dry for 15 - 20 minutes.
Repeat with your second canvas.
Decoupage over the top of your paper; coat the sides of the canvas as well. Allow to dry and then give a second coat. Allow to dry.
Add some Mod Podge to the back of the doily.
Place the doily onto the canvas and roll out with a brayer (if you have one) to get it to stick. If you don't have a brayer, use your hands and prepare to get messy. You'll see the Mod Podge through the doily, but don't worry - that will dry clear. Let dry 24 hours before hanging.
