As I promised, here's the yarn tail tutorial. There are five parts. These files are HUGE JPEG’s. Just a warning. They are very large so people can read them and see them. I have them uploaded here. EDIT: Images are resized and uploaded.

I forgot to mention! When brushing out the yarn into fur, after a lot of trial and error, I use a brush like this:http://www.barkessentials.com/images/Ancol-Wooden-Handle-Slicker-Brush.jpg
And it works great! Don't get the ones that have the "self cleaning" button on the back though. They get in your way. I used one, and wound up breaking off the cleaning part because it ate my wire bristles.
