I crafted a plains style quiver with a coyote pelt, some home tanned deer leather and some commercial grade cow hide for a core.  Green flannel and art sinew were used also.
The leather core was a bit too stiff and arrows fell out when I bent over.  So I asked the PA audience about this and they did not disappoint.  I have since placed a wadded piece of buck skin in the base of the quiver and the arrows behave nicely.  I also am more mindful of squatting rather than bending over when I have the quiver on. 
I wanted a strike a light bag but wanted to use the coyote face.  So the bag grew in size.  It is almost a possibles bag!  Extra string, pine pitch, a knife... who knows what I will put in there.  
Over all a comfortable quiver.
