The ones I have seen are very similar to a bed runner with a pocket in the ends. I'm sure if you look at epatterns or amazon books I have seen patterns and book. The idea is they fit over shoulders.. Somebody on this site has also made a jelly roll one with a slit to go over shoulders not sure if it was called a prayer shawl , I think it was to keep the elderly warm in a home. Sorry cant help any more.
