I'm going to apologize in advance here, because I didn't take enough pictures of the next step. I'll try to do a good enough job of describing what goes on.
By now, you should have a quiver of the length that you want, with a bunch of 1/8" round uprights sprouting from the top at regular intervals all around. Now's the time that the quiver comes off of the form. This can be kinda tricky, because the reed shrinks as it dries. It might be a good idea to have someone help you pull it off. It also might be a good idea to wax the form berfore you start, but I've never tried it.
Once the quiver is off of the form, sit down, and hold it between your knees to do the next steps. You need to bend the uprights 90º, and around the next upright to the outside. Tuck it in behind the second upright, and repeat with the next upright behind the first.
You can do this either clockwise, or counter clockwise, it doesn't matter which way you go. I bend clockwise, and proceed counter clockwise, but I'm left handed, so do what's comfortable for you.
Once you've made your way around, you can continue to spiral the rounds around the adjacent pieces. lay them together like a cable, going out, around, under, and in.
Pull them snug, but not too tight, or you won't have room to get the next ones in. When you're done, snug them up all around, and cut off the excess. Don't cut them off too short, or you'll be pissin' and moanin' as the ends pull through.
When you're done, it should look something like this.
Now, you have a quiver, but no way to hang it, that's next.
