From Forever Paris: "Marché Saint-Pierre is the largest fabric store in the world, and it sits at the foot of Sacré-Coeur in Montmartre. Seven floors, 3,500 square feet (325 square meters), creaking wooden floors, shelves stacked to the ceiling. Cotton, lace, tulle, upholstery fabric, ribbons, linings — the selection is overwhelming in the best possible way."
