I am a Red hatter. Some have got a pattern from a man's tie .I will take a photo of mine later and post it for you .I am off to Red Hats today
I made one using a sewing pattern with a neckline shape that was similar to the chatelaine, then added pockets on both ends to hold my thread and scissors.
I made one without a pattern, just took a fairly warm scarf and cut it to size to fit comfortably around neck area,and decorated mine with sewing machine, house with the roof appliqued on like a pocket for scissors etc I cut the length to just below bust, should be firm enough to hold shape, hope this helps
Not exactly sure what you are looking for. Added a link for a project. If you could upload a picture more of what you have in mind that would be helpful.
