I ran across this old post by accident, Butt I would like to add my answer....
First of all I would think I was qualified to answer, I have made a couple of Quivers in my Day and a few Armguards ta boot....
Yes anyone can make a container to hold Arrows, Butt to make something from a Quality leather that ya don't mind looking at and that you will have to will to your Grandchildren may take a little time and craftmanship....
Take my 4" Hunter Quiver, Yes I can make it in a day, I need some special tools to use on it, Some of which cost $30 a piece....
It takes time to lay it out, cut it out, glue it up, hand stitch it and then lace it up.
If ya add a pouch to it, More time....Etc
I have people tell me all the time that I don't charge enough, Well I'm not rich and I don't think most of you fine folk are rich either.
I have had people compare a Neat Q to my Quivers....
My Quivers are MADE IN AMERICA and they never see a machine....
So my answer is I don't think Leather Back Quivers are exspensive....
Especialy when ya by the right one and it last you a life time....
Sorry if I ranted on a little....
