Masking is a term which means "to cover". In the world of stamping it is used to bring images to the forefront by covering the main (foreground) image with a mask, and then stamping over it with another (background) image. This technique is easy, fun and very useful.

Choosing Mask Paper
Any paper can be used to create a mask, however, the thinner the better. I prefer using post-it(tm) pads because they are reusable, removable, thin, and relatively inexpensive. They also come in a variety of sizes. Masking films made specifically for stamping can be found in craft and stamp stores.

Creating a Mask
You may make masks of your favorite stamps before you get started on your project or make them as you go. To create the mask, stamp the foreground image onto the mask paper of choice with a dark ink. Cutting is the most crucial part in creating your mask. Cut just inside the foreground image to prevent "halo's". (If you are using a heavier gauge paper you will need to cut away more of the image.) Practice on scrap paper until you've reached the preferred effect.

Using a Mask
Stamp your first (foreground) image onto card stock. Carefully place the mask over that image. Stamp another (background) image over as desired. Lift off the mask to reveal the layering effect. Color as desired.

Or: You can also use multiple background images or colors. Just leave the mask on as you stamp and color the background. When the background is complete, remove the mask and color the forground image.

Storing Masks
Since you've invested time creating your masks you may want to store them for later use. A journal or notebook with clear plastic pages is an excellent choice. Just place and peel off later.
