This first one is from Bakerella. She has a tutorial on how to make a box of chocolates where the entire box is edible! How amazing is that?
Unfortunately for me, it's TOO amazing. I could never bake a marvelous piece of art like that. I must strive for the cheater's method.
If baking or heart-shaped cookie cutters are not your thing, then there's always my origami heart tutorial. It's perfect for tucking a sweet little note into! All you need is some red paper!
The Black Apple has some printable cutie-pie valentine cards available. Just head over to her site for the PDF link.
You can make a lego cupcake, for the lego lover in your life. I know a few lego aficionados myself...
How about some M&Ms with you and your sweetie on them? You'll need to plan this ahead of time for next year, probably, but now you know where to find 'em!
I'll add more ideas as we get closer to "the big day".
Have a wonderful day!
