I've already got a video showing the basics of how to whipstitch. It's a great way to sew up a stuffing opening in a softie, and that's what I demonstrate in the original.
When you're working with felt, the basic mechanics of how to whipstitch are the same. But felt is a little different than regular fabric - it's thicker and you don't have to turn the edges under. These make it a delightful fabric to work with (especially wool felt) but they also mean that there are a couple of new things to think about when you whipstitch on it. That's what I show you in this video.
