Wow, thanks everyone for the feedback. This really helps. It sounds like back, belly, and tail are the crucial areas for tying. There are a number of cheaper pelts missing a leg or two, or even a head, so I will pick up one of those.
Tidewater, thanks especially for all the detail; to a beginner, that's gold. Another of your responses came through my regular email via the site and I responded to that one before checking here. So, please ignore the redundancy. I'm still trying to figure out the navigation here, especially as this is the first forum I've ever joined.
By the way, is "Baitfisher" a tag all newbies here get? I sure didn't type that in at any point! Admittedly, my daughter did hook a heck of a catfish last summer on a worm we dug up in the garden...
Thanks again all. It's great to be sharing this addiction.
