Reg,
Although I'm not an expert, what I like to do to get my bugs "fuller" is spin and then stack. For example, after spinning a bundle of hair, without moving the thread forward, stack another bundle of hair on top of the spun hair. I use this technique when I'm tying poppers and divers in order to get a fuller collar and popper "face".
For the area where the diver collar is going to be, I spin the first clump of hair and then stack a couple more clumps on top of that. For the "face" of a popper, I'll usually spin the final clump of hair and then stack two more clumps on top of it.
Hope this helps,
Regards,
Alberto
