This almost has a Cirque du Soleil feel to it! Doesn't it look as if the dancer is dropping balls over his shoulder and then tossing them into the air with his foot??

Using scrapbook papers for an artist card background is not typical for me. I usually use old text, acrylic paint (using techniques such as crackle medium, sanding/distressing), or alcohol ink. I must say I prefer the free feeling that the "creation process" gives me as opposed to using a piece of patterned paper! To each his own!
