I'm sure there are other ways to sew this together, too, and you may find a way that works better for you. :) I tried a couple of ways, and liked this one:
1. Cut one of the stole designs from the panel. (It is not necessary to follow all the curves--just separate the stole from the rest of panel, effectively cutting a 12” x the width of the fabric strip. Fuse interfacing to back of this strip of stole pattern pieces, according to interfacing instructions.
2. Cut out right and left stole pieces, with interfacing attached. Cut along the edge of the printed stole shape.
3. Cut backing fabric into 3 strips, 6” wide by the width of the fabric. Cut one of the 3 strips in half so that you have 2 pieces approx 6“ x 22”. Sew one half to each of the other 2 strips, so that you have 2 strips approximately 6” x 66”. Press the seams.
4. Using cut stole pieces as a pattern, cut the backing pieces as copies of the front, making sure you cut a right and left piece, as mirror images of each other.
5. With right sides together, sew stole pieces together at top seam. (Sew just one center seam that is as long as possible, disregarding the angle-like notches cut into the pattern.) Press the seam.
6. With right sides together, sew backing fabric pieces together at the top in the same way, pressing
7. With right sides together, pin the backing fabric to the stole fabric.
8. Sew the stole fabric and backing together along the long inside and outside seams (leaving the bottom seams un-sewn). Use the small triangles at the center of the top seam as notches, carefully matching that center seam. There will just be two, long seams: an inside arc and outside arc. (No corners or pivot points.)
9. Trim the seam allowance in the curved sections to 1/4” or under.
10. Press the stole flat.
11. Turn the bottom seam on each side under 1/2” and press.
12. Using a ladder stitch, hand sew the bottom seams closed.
That's it! Enjoy your new stole... ;)
