OK. I used the file upload. Photos on my website will be there until I'm done for. But who knows. That could be tomorrow?
...oops. I uploaded the image twice but it didn't automatically become part of the post. I'll have to figure this out. In the meantime a remote website image link, to a Mule Skinner with a bushier hackle than previous examples.
At the base of the white wing, if you look closely, you can see a vaguely gray area. That's fabric cement worked into the base of the fibers with a sewing needle. That holds the fibers in place, radiating outward like a feather hackle, using only the hard tips of the deer hair. That's the part that doesn't flare when you pinch it down with thread. So if you want hard fiber hair hackles (that don't flare with thread) you need the glue.
