Stippled hearts! where each stipple "loop" goes wide and has a pointy indent in the middle like a heart.
I am terrible at "quilting" with my computer mouse, but this is roughly what I mean. It's easy to do. I can even do it on my ancient longarm with no stitch regulator! It looks much prettier in thread, and creates a very sentimental overall pattern that looks like stippling from a distance but communicates love closeup.
