I congratulate you for just coming home with one 10 yard piece of fabric, and if you had left it there, it would have "haunted" you. When a fabric jumps into my arms, it's a sign that it has to come home with me, no questions asked. You know very well that if you had left the store without it, then decided to go back, driving an hour each way, the fabric would have been sold out, or there would not be enough for your project. Buyer's remorse is not easy to live with and you have to remember that fabrics have a shelf life so you need to buy what you need and maybe a smidge more.
