The templates are so simple it's embarrassing.
Nevertheless, here are some 30 or so photos that show a step by step process any child can follow. The 3 little files are png files to drag and drop. They fit an 8.5 X 11 sheet of card stock, to print, but you will not need the templates, just use the idea instead. They are put there for your human comfort.
And I tell you what, if you were to take a moment and fashion such a card for your sweetie, it will be the best card they ever receive and I'm not kidding. It will be treasured, I learned, and saved. Forever. When the person dies their survivors will go through their things, and go, "no wait, what? what? this person got Valentines cards like this when they were alive? That's awesome! Man, I wish I had friends who gave me cards like this."
And it's a simple one too. Part 2 Doubles the awesomeness of this card, and Part 3 intensifies that!The super-clear photo instructions are entertaining even for those of us who would never hand-make a card, even for those who don't send cards of any kind, and even those who have a Valentine's-equivalent-of-Scrooge-like attitude about Valentine's Day.
