I use the same method that afishinado gave you. When doing this, to get the best results, you have to make sure the stripped side of the quill stays against the hook shaft (that is, the quill starts out this way, and doesn't twist). The easiest way to do this is by using a rotary vise. And of course, the feather must face the right direction, like it is in the picture, so the natural curve of the barbs curves them over the hook, not up and away from it. Sometimes when making the head I wrap the thread back over the barbs a bit if I want them to sweep back a little more.
