I'm terrible with a pastry bag and royal icing to decorate cookies. Just have no talent for it. I found this recipe and had to share it because the cookies turned out so well! Unlike other stained glass cookies that require hard candies that are, well, just too hard on a soft cookie, this makes a beautiful and edible solution. I did pipe the outlines in royal icing. Important: Use a paint brush and do a light coat first and let dry. After the first coat, you can daub on to fill up to your lines for a thicker coat. Cooking time is drying time.
