According to a video for the Hero Arts challenge this week - Stamp layering technique - which can be found here. I love the tips Shari gives when card making!
Here is my version. I should not have used a solid stamp but because I stamped on the wrong side of the paper, I got my pattern anyway, and luckily this stamp is the same on the right and the left! Note to Stella from the Netherlands - I used the papers you sent me for this - do you recognize them?
Here is a little close-up.
