I've applied Versa Mark to my stamp and then stamped the image on the black card stock.
I carefully dipped the cotton ball into the Pearl Ex then I dropped some of the Pearl Ex over the stamped image. Making sure to push it down, instead of swirling it around... I did that to avoid smearing the image.
Using a paint brush, I wiped off the access Pearl Ex and was left with this beautiful image.
Over the top of those three colors I dropped some "Crystal Copperstone Effectz".
I used a paint brush to spread the Pearl Ex over the card. Paint in the same direction with each stroke, in this case, I painted left to right, each time ending at the top right corner. I covered my stamp with Versa Mark and stamped the image onto the card again, resulting in the image below.
Here is the exact same technique on a piece of black card stock.
