Many times brides are lucky enough to carry a special handkerchief from their grandmother or great aunt or some loved family member. It is often their "something old." Brides normally carry it with their bouquet of flowers.
Recently we saw the bride give it to her groom to put it in his pocket. This is a great idea for two reasons. One it doesn't get ruined if the flower stems rub and stain the delicate handkerchief. And secondly, it is very sweet that the groom offer his bride a cloth if she starts crying during the ceremony!
What a neat idea!
