Thanks for the input guys. I did some taxidermy when I was in highschool, a very long time ago...but I believe I recall using basically a cotton stuffing similar to what might be found in some pillows. I rather like your "minimal stuffing" idea. Do you have any suggestion on what I should use for the innards? I am trying to decide between sewing the eyes closed and putting glass eyes in, though I'm leaning towards sewn shut (I'm a tad creeped out by an animal eying up my crotch!)
