Hey, thanks for the paper cutting love!
So, a few of you asked in the comments how to do this, or where to learn how. Well, I can't pass up the opportunity to direct you to eMailorder #8 where you will find directions specifically written for first time paper cutters. You'll get 4 awesome paper cutting patterns (if I can say that about my own designs, which I just did) and a recipe sure to delight. Please note the little heart design there, perfect for your special valentine, it's just the right size for a card.
This is a PDF that you print out at home—it's not mailed.
