Oh yes brother, keep posting and preaching these tips. Heat up the botkin to make the hole, and take your wife's crocheting hook to pull the legs through it. I'm using a .410 brass cleaning brush as my dubbing brush too. And I love the shirt with Sasquatch with his rock and roll fingers high. Yes, I'm that old. Rock on brother.
I have a bait needle for putting boilies on a hair rig that works great for legs. Its shorter than your long one, a bit smaller, with a smaller head for the latch. In a foam or deer hair body you can even take a single strand of black bucktail, pull it through and trim to the length you like. The .410 bore brush is a good idea, although I do use a lot of velcro. Both have their place. Keep em coming brother!
