Trad,

I'd really look at sending them off. "garment quality" tans are hard to achieve with most home tannning solutions. I've been around tanning for 30 years, and to tan something to mount, or for a rug are one thing, but its just tough to do for making clothing. For the stuff you want to make something out of (hat, pillows), I'd send to K&K in Michigan. For the others get a tanning kit and do that yourself. Maybe wtlhaven can chime in.
