A Roman blind is provided which includes a head rail and a web of fabric material attached at a first end to the headrail. A pair of lifting cords extend from the headtail to a second end of the fabric web, to which they are attached. Two columns of guide elements are provided wherein each column guides a respective lifting cord. The guide elements of each column are arranged also to provide horizontal rows, about which the blind folds when raised. A pair of connecting tapes are disposed between the head rail and the second end of the fabric web. The tapes are secured to the fabric web by the guide elements, whereby unfolding of the fabric web is constrained by the tapes to a pre-defined maximum spacing between vertically adjacent pairs of guide elements, the maximum spacing between the vertically adjacent pairs of guide elements being less than the corresponding length of fabric web disposed between them. The blind further includes a backing sheet to cover the lifting cords, guide elements and connecting tapes to hide them from view.
