A dust cover is essentially a piece of paper, usually strong kraft paper, taped to the back of the canvas. This is a cheap and easy way to protect your canvas.  Make sure the sheet of kraft paper you buy is bigger or equal in size to the framed canvas. If the kraft paper curls after you cut it, flatten it under a heavy, flat object such as a book or glass pane.  Once the kraft paper is flat, you can now attach it to the canvas. Using an ATG tape gun, apply double sided tape to each stretcher bar 1/8 of an inch from the edge. Do this for all four sides, and try to keep the tape in a straight line. Place the kraft paper firmly on top of the stretchers, ensuring that each edge of the kraft paper lines up with the edge of each stretcher bar.  Press the edges firmly down. If there's excess paper, you can trim it with a knife or scissors. Now, you're ready to hang the canvas!
