A stamp positioner allows you to place a stamped image precisely where you want it on the card. Positioners are available in various styles and price ranges. The most common positioner is an acrylic T-square ruler. To use the positioner, first stamp the image in the corner of a translucent piece of paper. Be sure to line up the left and bottom edges of the stamp with the edges of the paper. Use the stamped image to decide where you want to place it on your card. When you determine your desired position, hold the translucent paper firmly and line up the corner of the positioner with the corner of the translucent paper. Remove the paper, position your stamp in the corner of the positioner and stamp your image. Positioners can be very helpful when creating a repeating border or in correcting incomplete stamped images.
