I am thinking about lining our aisle with satin sashes draped from sheppards hooks instead of tulle. It would take 7-8 to do a 50-75 aisle, which is outside. I am thinking about using a satin aisle runner, tacked down with garden fabric tacks, and have it in place before the ceremony. The satin sashes would line the sides and block off the front of the aisle and prevent people from walking on the aisle runner before the bridal party marches. I know most people say skip the aisle runner outside but I love the look and really want it. I am thinking about ordering the white satin aisle runner from linen tablecloth:
