I took some index cards and added drops of the following, bottled ink colors onto the cards: Teal, Pearlescent Aqua Blue and Walnut ink . Then, I pressed the inked cards together and achieved a nice mottled effect.
The cards all have a beautiful sheen which doesn't show up in the photographs. Next time, I may create the cards in a lighter color
I stamped the lower left-hand card with silver pigment ink - And the lower right-hand card with white acrylic paint. What did you experiment with today?
