Once I finished the lacing of the body of the quiver, I just made two simple knots at the bottom, then trimmed the ends off.

Now that I did that, it was time for the bottom.  I used a section of leftover leather and first cut a square.  Then I trimmed it down until I got a close form.  I made sure to mark a spot on both the quiver and the bottom, so my cuttings would line up, since it wasn't perfectly circular.  The bottom turned out to be roughly 3.25" in diameter.

Once I had my bottom cut, I then placed it onto the quiver, and marked corresponding places for holes on the circle as well as the sides of the quiver.  I then drilled the holes and started threading.  I made sure to leave a lot of slack so I could work.

I then tied it off just as I did with the quiver body.  Once I had one knot made, I was able to just tighten everything down really good and make the final knot.  I probably made a mistake in tying one of the knots on the outside, but that's the only way I knew how to do it.  And it's my first quiver I ever made.

Here's the final result.  I don't have a handle or strap just yet, because I'm not sure how to make it.  It's a very simple quiver that's made to serve a simple function and not win style points, but maybe in the future I'd like to line it with wool and maybe dye it a little darker, but first I gotta find out how to do a strap!

PS - Anyone know how to smooth the edges so they don't look so rough and frayed?
