Here on the blog, you'll find information, background and more instructions. To get a stole, you can go to my shop at Spoonflower and order a printed stole sewing panel.
As it says on the designs, I recommend ordering them on the organic cotton sateen--which is both wide enough to accommodate the design and a lovely (elegant, even) lightweight fabric. Besides the panel, you'll need to purchase interfacing. (I use Pellon's featherweight fusible apparel interfacing.) And, depending on the panel you choose, you may also need to purchase a backing fabric; I use Kona quilting solids. (The colors I used are indicated in the Shop.)
Then, the pattern is pretty simple to sew. Ironing the fusible interfacing on probably takes the most time--there are about 4 seams to sew, a little pressing, and some final hand-stitching. I'm not great at sewing, but found it all quite easy. (Of course, I also dreamed up the instructions...) You can see the basic instructions here.
If you sew one, I'd love to see a photo of it (and, even better, a photo of you wearing it!) It'd be awesome if you posted one in my Flickr pool...
