The artist says, "GERMS! They're everywhere. You can't avoid them, not entirely -- though one would hope you'd avoid syphilis, of all things -- so why not incorporate them into your decor? If you're into science, or just germs, or cleanliness, or if you're a hypochondriac, you might like to see your interests/worst fears immortalized in stitchwork. Luckily, now you can."
I must say, these are great conversation pieces to hang in your home.
