I love this small, cute, quick Valentine Card! You could make up a batch of these in no time. The designer, Krish, calls for card stock in her tutorial which you can find here. I think this would work beautifully with layers of scrapbook paper glued together, a ‘vintage’ Valentine Card, or even cards cut from those crafting foam sheets. The foam sheets would be more forgiving and would work better in the hands of youngsters.
The nicest thing about this is that you can make one for your sweetie in any color you like, personalize it, and have it all ready to give on Valentine Day!
