As I suspected, this jacket was constructed from one 37″ scarf. I’ve drawn a few quick diagrams so you can see how it goes together. I think this would be pretty easy to reproduce. Keep in mind the size of the scarf, as this 37″ one fits about a 34″ bust, if tied with the two halves meeting.
I’m going to give simple directions, but I’m assuming you know the fundamentals of sewing – basics like right sides together to stitch seams, and things like that.
First, the cutting diagram:
Note that it is symmetrical. Here are the measurements for a 37″ scarf. You could adjust these depending on the size of your scarf. And because the diagram is symmetrical, I only labeled one half of it.
Cut out the 5 pieces. For the body, make two slits, 8″ as shown. These will be the arm holes.
Take the two sleeve pieces. As you see them on the diagram, they are up-side down, with the sides being between the ties and the extra piece. Stitch the sides together to form each sleeve. .
My jacket is hemmed along the front opening and along the bottom. If you want to hem yours, do it now.
To make the shoulder seams, you will need to put 2 or 3 pleats in the front like this:
Then fold the front shoulder to the back shoulder and stitch on the wrong side. Then stitch the sleeves into the armholes, placing the point on each piece at the shoulder .
Make the ties by stitching them on the long ends and turning them inside out. Attach to front. Slip-stitch the neckline to finish it.
And that should be it. If anyone tries this, let me know how it goes. I’m now on the prowl for the perfect scarf myself!
