Lovely quiver you made there, well impressed!
I quite like the style of the native american indian quivers, a full arrow length soft but stiffish bit of leather folded lengthways with a stiffening rod sewn in the join with leather tassels top and bottom. A quite long strap holds it at hip height and it can be worn in several positions. The arrows are kept quite secure even if the quiver is tipped downwards.
