Abstract
An improved Roman shade has a series of parallel, generally U-shaped ribs which grip the shade fabric at selected intervals to provide a series of cascading transverse pleats. Each rib is formed by a pair of legs connected together at a proximate end to form a top and abutting one another at their distal end to define a fabric receiving cavity therebetween. At least one cord carrier is attached to the top or one leg of each U-shaped rib and connected to a spacer cord.
