We made these Elmer's Glue Background papers our April meeting of River City Rubber Stampers.  I tore mine up to make these accents for a batch of cards.  It is a fun and easy technique and you get great results.  Elmer's Glue, Perfect Pearls and black glossy card stock.
Scroll down to see one I make with white glossy too.  It's cool but not as dramatic as the black.
email me if you want the complete directions.
