Make a Monument Plaque
You need a somewhat padded work surface, such as an ironing board or a folded towel. Center a print-out of your text, upside-down, on a foil cookie sheet, using masking tape to hold it in place. Then use an ordinary ball-point pen, and trace over the lettering. Turn it over. Now that lettering is raised like a real plaque!
Next, trim away the outer rim of the cookie sheet, carefully -- the cut edges are sharp! -- and then cut along the edges of the print-out. Use a black Sharpie to make your lettering stand out. Remove the print-out and draw a 1/2" line within the perimeter of your now 8-1/2" by 11" plaque. This line is easy reference for your next step of covering that exterior edge with black electrical tape.
To add rigidity, I cut blue insulating styrofoam the same size, covered its edges with black electrical tape, and used tacky glue to hold the foil to the foam. Lastly, I added 4 screws to the corners for a finished look.
