A very simple stamping technique is called off-stamping. If you've never heard of it, it's inking up a stamp, stamping it once, and then, without inking, huff on the stamp (exhale moist breath), and stamp again. The result is a lighter image. You can use this technique to give the illusion of movement or depth.
Sometimes, off-stamping works fine, and other times, it doesn't work so well. Different inks...and even different colors of the same brand of ink...will respond differently. I find that the intensely colored Hero Arts inks off-stamp great! I kept huffing on the inked stamp, and it kept putting down ink in ever-lighter impressions.

The red version of the card was made with a single inking, but the green ran out faster and required two inkings, but still. It made me love the Hero inks even more.
