Online Card Classes Days 3 & 4 featured watercolor stamping. Great techniques again, so much to learn-so little time. I think that I will need a lot more practice to get some of these techniques down :) I tried to create a card that was similar to one created by Jennifer McGuire. The stamped image is outlined with a medium that resists watercolor like rubber cement. Then you watercolor a background, the technique is really beautiful. This technique was actually in Day 2 but I am a little behind.
