Black and White Silhouette ATC cards

I decided to make a series of cards in black and white.  My favorite part is making the back round.  I used acrylic paints in gray, white and black and applied them with a brayer.  I wanted to get somewhat of a swirled marble effect.  After the paint was dry, I used a rubber stamp in a fleur design and stamped it all over the page with embossing ink.  I sprinkled it with white embossing powder and heat set it.  I them cut the whole page up into ATC size cards and did the rest of the individual designs.  Most of the shapes are cut from various cartridge on the cricut.
