This card example - is made using the original technique... a couple of nice stamped images in opposing corners and a watercolor frame around the edge. I used green pen to emphasize the watercolor window.
The "Relax" card was stamped in the same fashion (images in opposing corners) but instead of using a yellow marker to highlight the frame I used a coordinating color to the watercolor frame. I think it helps set off the flowers a bit more and gives it a bit more substance.
Just a note - to stamp the flowers I colored the stamps with markers then spritzed with Shimmer Mist and pressed onto the watercolor paper and left for a few seconds. This creates a lovely watercolor effect and a slight shimmer which you can barely see on the flower in the upper corner. It shows up much better in person.
And for this final card - Birthdays. - I interspersed the stamped images not just in the corners but around the frame and I tossed in a tiny sentiment as well. The frame was again highlighted by a coordinating color - Rose Red in this case.
So there you go...a couple little tricks to add to this fun technique. Hope you give it a try - you'll be amazed at how easy and fun it is to add to your cards.
