I saw this technique on Rena's blog and had to give it a try.
First stamp small images with light colored dye inks on white card stock and let dry.
Choose a large bold or solid stamp and stamp with VersaMark ink, cover with clear embossing powder and heat set. Let cool.
Cover the entire surface with a darker dye ink and let dry. You can brayer on the ink or do direct to paper (what I choose to do).
Wipe off the ink from the embossed image.
Use a darker ink to add stamped images to the non embossed areas if desires. My light isn't very good, but you can see the lighter stamped images "emerging" through the embossed image.
I mounted by emerging colors piece onto a blue on white stamped piece then onto black card after adding black ribbon, a black paper flower and a white flower brad.
