Peacock herl can be tough to work with sometimes. I've found that if you take two strands (or as many as you need) of herl and twist them together on your thread exactly like you would with dubbing, it's much easier to work with. Not only does it make the herl stronger, it helps towards keeping it secure when you wrap it around the hook shank.
Keep at it!! That's the best advice I can give you. It took me awhile to get used to tying. Tying can be frustrating at first, but once you get the hang of it, it's the complete opposite...
