Here is a photo of how I displayed some in my apartment three years ago (I can't believe it was that long ago). All you need to do is cut out the couples and glue them to some hearts you cut out!
And then here is what the valentines look like! I love all of these couples so so much!
If you click the picture it will take you to a website so you can download the pdf.
I hope you have the best Valentines Day!
