Packing hair, what are you trying to do and how do you do it?
The concept is to get each bundle of the hair at the hook shank to be as close together as possible. When you pack hair, what you are really trying to do is move the place where you tie it in along the hook shank back against the previous bundle as tightly as possible. Anything you put on the shank in front of the hair that ends up between the bundles degrades this process.
To do this as efficiently as possible, you want to apply pressure to the thread wrapped in front of each bundle, not to the hair itself. If you make a few, one or two but not more than three, wraps in front of the bundle, then push on the thread, you can feel the whole mess slide back along the bare hook shank. The reason some tyers add a half hitch in at this point is to keep the thread tight during this process. I’ve seen some guys use a drop of head cement (not CA glue) at the base of each bundle too. All of this is up to the individual tyer, use what works for you.
You absolutely need a solid blocking wrap at the back end of your spinning area to push against. A few tight wraps with a drop of cement added makes this work quite well. If your blocking wrap slips, you can’t pack the hair tightly.
If you can get your thumbnail against the hook shank and use it to slide the bundle and thread wraps back, then by all means do that. If you can’t, then use a tool. Just remember that the tool needs to push on the thread, not so much on the hair. If it’s not sliding against the hook shank itself, you won’t get a solid pack. The brassie type tools seem to make better shank contact than the single hole packers do but used properly, they all work.
If you use a tool, push straight back as far as you can, then wiggle it a bit from side to side. This help the hair meld together. If you don’t use a tool After you pack by hand, brush the hair back and forth a bit with your fingers or a comb between each bundle.
You have to use enough hair but not too much. That amount varies from tyer to tyer. You’ll just have to practice. A ‘pencil sized’ portion is the standard reference, but some of us prefer less, others much more. Too little hair, and regardless of how much you pack it, you won’t have enough in each bundle to create a dense body. Too much hair, and it doesn’t flair well and your thread won’t get close enough to the hook shank… all kinds of problems will ensue. Only you can figure out how much will work for you.
Cleaning the hair. Any underfur left in the hair will adversely effect how tightly it will pack and how well the hair will flair. Many great deer hair tyers are fanatical about cleaning their hair before they use it. Everyone I’ve seen do this well pays some amount of attention to it. Combing is the minimum I’ve seen from really good hair spinners. A lot of above average spinners get by with just a few tugs with their fingers. Up to you.
Practice. Your first bugs look great for the first tries. They will get worlds better after the first hundred or two. No real shortcuts. You been told pretty much all you need to know already. Practice is the only way to get really good at this.
Trimming. It’s a skill. It takes practice, good hands, a vision of what you want, and the will to learn it, just like any skill.
Here’s a little tip that may make your bugs come out better. You’ll be amazed at how much fuller and easier to trim your bugs will be if you steam them before trimming. Try spinning several, then boiling some water in a tea kettle and holding the spun bodies over the spout as the steam escapes (us hemostats to hold the hook, steam is hot).
I know lots of guys who don’t bother with it, and their stuff comes out great, but try it and see if it helps you.
