You can also make a spray of Pearl Ex, powdered gum arabic and water...this will make your CS shimmer (I don't care for hairspray smell, or the stickiness of it!).
Also try inking up a bold stamp, hold arms length away and spray with the mixture to get a watercolory-shimmery look. Pearl Ex Aztec Gold is a good color for any image.
Let me know if you want the mixture for this and I will dig it up!
