Stamp your image with either Craft ink or Versamark.
Dust on Heat & Stick (just as you would embossing powder).
Heat only until the powder turns clear.
Dust on Dazzling Diamonds glitter (or other).
Heat set.
The glitter is now exactly where the stamped image is! It's very cool.
I don't have Craft inks, and like colored images, so I stamp with Classic (using a Stamp-a-ma-jig), wash the stamp, stamp with VersaMark, then do the rest of the steps.
Give it a try!
