Decorative Tape and Stamp Positioner Usage

For the above card, I used decorative packing tape to provide the background. I have previously shown tape as a striped background and as faux photo corners. This was accomplished with 2 strips of tape on a white background.
The center image was stamped with white ink onto black card stock. Once it was dry, I completely filled in the image with white gesso. This was a technique we did at Club Scrap's Retreat. It is similar to techniques we did years ago with colored pencils.  After the gesso has dried, stamp the image again, using a stamp positioner, in black ink. Using acrylic paints, paint the image. Once the paints have dried, over stamp the image again in black ink, using the stamp positioner for placement.  The image can be stamped several times depending upon how dark you would like the image.
Decorative tapes come in a variety of colors and images, making it easy to mix and match with your stamps and techniques. Have you tried using a stamp positioner? What is your favorite technique?
