I don't know about the Martha Stewart cookies, but if you decide to give heart-shaped cookie cutters out as favors, we have some that sell for $1.95 for a set of three cookie cutters. They can be found in our eBay store:
More people than Marth Stewart has these favors. You can do a search online and find them. They have pictures all over the internet of these. I got them for my daughter's Sweet 16 from a place that does them like placecards and even puts the guests name on them. Since her theme is Cinderella, I chose the Carriage shaped cookies, they are decorated nicely and even has the person's name on it. It is great for a placecard on the plate and also for a treat for her guests while waiting to be served. They are reasonable also. Don't just limit yourself to Martha Stewart, go online and search cookie favors and you will find them.
