Do go down and get it up and try it on.
I made shawls for the nursing home that were cut from fleece 26" wide. Then I turned under and inch top and bottom. I fringed the edges I have also seen patchwork shawl 72" by 24". They had pockets put the last 6 inches of the ends of the shawl.
Nancy's notions catalog has a wonderful Patchwork shawl more of a U shape. it would be a Christmas tree skirt with just a little shaping and the neckline is more of a U rather than a circle.
But first try on that Christmas Tree skirt, It may be wonderful and work so perfectly and be your very own design
