You can interpret this in many ways. You can do a masking technique with your stamps, use an image with a mask, use a mask with your spray inks and mists, or use masking tape on your finished project.
I've made a valentine card. A bit different from the "norm" of course. The masking in this project is on the little 1/2 heart down the side.
I used the offcut from my grumpy card made a few days ago. The well sanded black/red coredinations. My TH mini masks and some SU! whisper white ink pad.
The image is from Smeared Ink. The Fire goddess. Stamped in the same white ink and heat embossed with red sparkle embossing powder.
I stamped the image on black card for a change. A "negative image" in mind. Then with white and red pencils, added colour then edges torn away. Some little red and black gems added for some more firey sparkle.
The shapes are all cut by hand including the black card base.
Inside didn't get left out from some ink either
