Here's a couple more cards from the Jessica Sprague card class.
This one was fun. It's not really my style, but I love the technique. You print out a transparency and then use a gel medium to transfer the image onto a piece of cloth. Then put that piece of cloth on the card.
This card involved using water colors and a photoshop brush. The watercolor portion was just the kind of watercolors you bought for elementary school, then she/I took a piece of shelf liner and painted on that and pressed it on top of the water color part to make that interesting texture (the little square looking part)
I just love how she is using so many mediums that I would never think of. Anyway, if you haven't signed up for her free class, you should. It's not too late.
