I cannot answer your question but I do remember a baby blanket by Martha Pullen or Creative Needle (?) The top inset was one piece of fabric, perhaps 10 inches wide, with several rows of tiny pleating or dense shirring (1/4 or 1/2 inch apart) running the width of the blanket. Seems like it was part of a Christening gown ensemble?? I believe the inset on the one I am thinking of was actually pleated on a smocking pleater then smocked. The smocking added design and held the pleats together keeping them from ballooning. It was beautiful.
