For my card I made a mask with a heart die and then sponged Distress ink spun sugar on it.
Then I stamped a swirly twig with leaves and heart several times, to fill the heart. It's from Imaginisce (heart vines)
I used red pigment ink to stamp it, then filled in the hearts with a red marker and used grey markers to give it a drop shadow, as if there's dimension on a one layer card.
The Love you is from Technique Tuesday (say it -love you by Ali Edwards) and I used Versafine black onyx to stamp it.

I've added a link to a video I made about washi tape, different shape, same technique, and a close up for the shadow...
