Ok, I had no term here so I am calling it backwards masking! :) Here is the "how to" segment showing how to use sticker backing as a mask and then "stamp" with it to create a backwards masking design. I chose
the Denim Blue Glimmer Mist by Tattered Angels for this layout. I don't explain things well so I have photos for you.
***Click the images to see them full sized*** Step 1. First comes the masking part. Pull the backing off the flourishy chipboard shape
(it is one of the Glimmer Chips from the Tattered Angels set called "REGAL"). This backing is really shiney on one side and the other side is more paper-like. Add some repositionable adhesive on the "paper" side and then press it to the area of your paper where you would like the design.
Step 2. Spritz with the Glimmer Mist til you like the color density.

Step 3. Carefully remove the mask (which is now covered with wet misty blue and move it to a piece of wax paper or parchment.
Step 4. At this point you can place a piece of paper, fabric, or any other porus material over the damp glimmer misted mask, press carefully, and remove. The mask still has the removable adhesive so it will stay on the wax paper and your paper or fabric will have the design on it. I used a piece of thick canvas for my layout because I wanted to cut squares that would have a hint of the design on them.

This is the masked design area of the patterned paper as well as the canvas strip. I took these photos on my desk rather than outside so you can't see the glimmer but I also spritzed them with
the Gold Glimmer Mist so its really pretty in real life. :)
