Thanks for your comments! This is my first posted card!
Use glossy cardstock. Cut your cardstock to the desired size. Put some water and dishsoap (any kind) in a bowl. Blow some bubbles through a straw. Put a few drops of re-inker ON TOP of the bubbles and blow a few more bubbles while you hold the cardstock over the bowl. You basically want bubbles with color in them to stick to your card. Set it aside for the bubbles to pop, leaving the color behind. TIPS: once the ink sinks to the bottom of the bowl it won't leave any color. Darker colors work better, some stay "on top" of the bubbles longer than others but Brilliant Blue is almost too dark. Positively Pink will work but it's lighter. (Forget Pretty in Pink) Brocade Blue works well.
