Thank you for the explanation, along with the visuals...I am a visual person.
Have to admit that the Pillow Panels were not what I had in mind. I go back eons (or so it seems) and I used to make pillow cases with fabric that was solid (for the most part) with a strip of clowers or whatever running along the salvage. All we had to do was sew around two sides then hem it. I was in the 9th grade and must have made dozens. My mother still had a couple sets left when she passed two years ago!
