Pretty easy to make your own pocket quiver and I made one long ago using brads to hold it together. Worked great.
I also bought a Go Lite quiver from Hidehandler that is flat like a pocket quiver but is a side quiver. Had one made without the pocket and with two straps with snaps. It holds a few arrows tight and can be set close to the back of me so I don't hit anythig with it when I walk through skinny areas. Made of saddle leather and is the best I have ever seen of its type. Much better than an open pocket typical side quiver. Like the flat pocket as it could hold two blade broadheads or field points and can be used easily for the back yard, 3-D target shoots, or even hunting as a person, especially with a pair of pack mocks, could sneak up on a cat or even a mule in a briar patch. Steve Catts is busy so it takes time for him to make one but its worth it. Look it up - you'll like it.
