Although its not one I made myself, my favorite hunting quiver has been the mini CatQuiver. Since living out here in Colorado, I have been doing alot of backpack hunts and the mini catquiver is perfect. I can strap it to my backpack and it protects the feathers from getting crushed or wet from rain/moisture.
I have made several back quivers, but I find they are not very conducive to hunting. My next quiver I make is going to be a "Stalker" style quiver that rides horizontally by your side. I carry my mini cat this way alot, and it is really nice when making a stalk. The thing I like about the cat is that the strap is quickly adjustable, so you can cinch it up tight to your body quickly and quietly
