The Triple Cube Pop-Up Box Card is proof that the best things in life come in threes, and also in small cardstock squares you’ve been hoarding in your scrap drawer for two years. You know the ones. The little pile of “too pretty to throw away, too small to do anything with” pieces that have been quietly judging you every time you open that drawer. Well, today they become art.
This card is a total showstopper, and the secret is that it looks far more complicated than it actually is. Three connected cube sections fold out into a sculptural, dimensional display that practically arranges itself. Pop a flower on top, add your sentiment, and watch someone completely forget they’re having a bad day.
The best part? It fits right into a Medium A2 envelope, so you can actually mail it. No “sorry, you have to come pick this up in person because it’s the size of a small appliance.” Just fold it up, seal it, send it, and prepare for the excited “I Love It!” phone call.

I love your Home Page. So many of the demonstrators have changed their home page/blog recently and the format is not welcoming and not easy to access their projects. Your website is fantastic and so easy to navigate.
Thank you for all your wonderful projects.
Thank you so much for sharing printable instructions and your videos on how to make these unique cards. I appreciate you so much!
