On the left side, I first applied a fairly even layer of paint. Then, by pressing the short side of the credit card into the paint (slowly and with some pressure) and lifting straight up, I got a fabulous texture of delicate veins and lines. On the right side, I swooshed the credit card back and forth like I was frosting a cake. Applying varying pressure results in a gradation of color and texture, as well as a fun pattern.
Here is a close up view of the left side.
It's likely that some or most of these backgrounds will end up covered by other media, but a good foundation is essential and sets the tone for the rest of the page. These backgrounds scream "energy," so I can't wait to see what happens next.
Thanks for popping in!
Supplies:
Strathmore Visual Journal Mixed Media vellum finish; Liquitex Basics acrylic paint: cad yellow deep and cad red medium; old credit card.
