Last time, I had pinned all the layers together, and stitched them into what will now be treated as one piece. So, each pattern piece has a layer of fashion fabric and a layer of coutil that have been carefully sandwiched together. Because my markings were made in white pencil on the coutil layer, I can still see my stitch lines and identification on each piece.
So I put it on a pillow to see how it was coming. There are no bones yet, so it does pucker and squish, but I am happy with it so far!
