I have to agree with the above two posters.
The stalker/rover style side quiver is my favorite.
I sew a 1/2" strip of leather to the bottom and use a 1/4" piece of poplar for the bottom, with 1/2" foam on top. The wood is inserted from inside the quiver and the leather strip holds it in place. The bottom can be removed, but to be honest, I've never accumulated enough crap that I've ever found that necessary.
Some reasons I really like them, are the ease of use, and the ability to get through dense brush unencumbered. Some side benefits though, are that, well at least mine, have enough room in the opening to throw a bottle of water in, so I don't have to carry water in some other fashion. I also add a pencil holder to the shoulder strap for 3D shoots, and a pouch to hold small essentials and snacks.
If you make them yourself, read this:
Not to pick on Bladepeek, but I would suggest that you attach the shoulderstrap to the top of the quiver more parallel to the quiver. I angle mine at about 45*, but either way, you want to avoid attaching it perpendicular like the quiver in Bladepeek's post.
The reason for this is that the quiver will have a tendency to hang horizontally when on your shoulder, which may cause you to dump your arrows out of the top of the quiver.
This advice comes from personal experience. My friend has a quiver with the straps at the same angle as Bladepeeks and his only complaint is that his arrows get dumped if he's not careful. My quivers are almost identical to his and I've never had that problem, but I attach mine more parallel to the quiver.
My friends fix is to weigh down the bottom of the quiver.
I hope that makes sense. Sorry Bladepeek! It's a beautiful quiver. Just thought it was worth warning him of the possibility, if he hasn't started making them yet.
