Can I just cut a hole in the side of the quiver and whip stitch it?
I've got a fur in, tube type quiver made from bear hide.  If I sling it on my lower back, I could cut an oval on the side facing away from me.  Whip stitch it and use that as an opening to pull arrows.  
Whatcha think?
My elm trees are getting a little bare as I keep trying to split branches for this project.  Not sure this rock elm/chinese elm hybrid is up to the stresses of bending and shaping.  My only other options are wild Rose's and pussy willow.
