This is a follow-on to the post about Mary Dette Clark suggesting that a pro should be able to tie a dozen catskills in an hour.

My assumption is that all materials are laid out a head of time. My question is, how is this done?

Let's say you're tying an Adams:
I can see setting out say a dozen wings, but how do you keep the wings from floating around all over the place?
Does a pro set aside a dozen different sets of spade feathers?
Do you set aside a dozen small balls of dubbing?
How about the hackle? How do you keep this from floating around?

Enquiring minds have been wondering about this for awhile.
