A pearlescent honeycomb material and an apparatus and method for making expandable pearlescent honeycomb structures suitable for use as window coverings. In one embodiment, a pearlescent material is prepared and then folded into tubular strips. These folded tubular strips with adhesive lines applied to them are fed continuously through a cutter which cuts them into predetermined lengths. The cut strips are then accelerated to a stacker for further processing before the next cut strip arrives. In another embodiment, webs of material are fed continuously in a downstream direction, adhesive lines are applied, a middle web is slitted into strips, and the strips bonded along opposite edges to the outer webs. By choosing for the outer webs transparent or porous material, and for the middle web opaque material, a light or air controlling honeycomb structure results.
