Blessing Stones At Your Beach Wedding: Why not try something different when it comes to guest sign in! We suggest providing a basket of smooth gray bed rocks, a basket, colored sharpies and instructions. Let your guests know they are to write a blessing or congratulations note on any rock of their choice. Display these keepsake rocks in your home as a reminder of your beautiful wedding day, surrounded with your family and closest friends! Let their words remind you of their love and support of your marriage!
