Ooo, you picked my card!
How cool is that! Thanks, Roxie.
If anyone wants an easy way to do the diagonal strip, take a straight piece of card stock that is 5-1/2" long and the width you want the strip. Lay it across your card at the angle you want and glue it down; then turn over and trim off the excess on the ends. (Basically, this requires no figuring of angles, etc. - I don't do math!) If want the strip layered, do the layer before you glue.
