Here's the pattern, ready to be enlarged. The quiver I built for my wife is about 16 1/2" long.

The dotted line is the side profile, the wedge below was added because of the bulge of the quiver, which would have let it appear narrower than intended.
Holes were punched to lace the quiver, of course it can be sewn as well - it's just more work and takes more time. I finished the quiver in about two and a half hours.
Holes were spaced about 1/2" (a bit more, 15mm).
Rings were integrated into the lace (lacing the teardrop-shaped bottom is a trial and error procedure), and the quiver was hung from the belt loop using the same leather lacing. Of course, with more time, leather straps with buckles will be substituted.
Decorative rivets almost 1" in diameter were added to spice the quiver up a bit. Fancy decorations were not in order, as it was meant for a tournament, where lots of rain were more than likely. The way things are, the rain never came.
The quiver was impregnated with gun oil, which prevents water stains and hardening, at the same time dulling the pale white colour of new leather to a warmer tone.
Here's the quiver in use. Click the thumbnail to enlarge it.
