I love this little bird stamp from My Paper Moon.
I used the black dotted paper to make the card background. I stamped a piece of red cardstock with a lip stamp, using versamark, so it came out like a watermark (although you can't see it in the scan). Then I tore it and attached it to the background.
I used a nestability die to cut out some white cardstock, then stamped the cool cat in the middle. I colored him with copic markers. I stamped again onto the black dotted paper and cut out the heart, which I attached to the cat. The cat is made so that he's easily cut out, and you could use pop dots to put him onto the background and give him some dimension.
I attached the whole thing to the background. I stamped "I love you" onto white cardstock, then used a red marker to faux stitch the top and bottom. I attached this to the bottom of the card. I stamped a sentiment in the inside and I was done.
