I stamped the cut out heart with a large Rubber Stampede background stamp that I have had for ages and really love. It always inspires me when I bring it out of my stamp drawer. It's so detailed and the results look just like an etching.
The heart shape just required a little inking around the edges to finish it off and give definition. I mounted it on 3D foam and resisted the urge to do anything else to it apart from the sentiment and 3 acrylic gems.
