Beaded Tin Foil CardTechnique by Marjie Brandeen
This is a card I did for a class at Fun Stamps in Lynnwood, WA. It's not a new idea, but it's easy and looks more complicated. The class really had fun with this one.

Here is a technique I did a while back with Colorations paint, but have also done it with Twinkling H2°'s and watered down acrylic paints. Just be sure to have some metallic colors in the mix.
Use a few colors that blend well together and put randomly on heavy cardstock or watercolor paper and spray with water. Take plastic wrap and set on top making sure you have plenty of wrinkles in the plastic wrap. Set aside to dry completely. Remove plastic wrap only when completely dry and you will have a beautiful background.
