Take a little water bottle and fill it as full as you can get it with the bags, stops a arrow pretty good.

I've stuffed gallon milk jugs too.   I have a burlap sack full of walmart bags that stops arrows pretty good.
Good idea.

I use a feed sack filled with bags as well......

Field points?

I'm working on a new dog bag target now.  Never thought to stuff them into a bottle, I'm going to use that.

Years back I posted an instruction for making a burlap ball to stuff with anything you want. Great fun to shoot... it rolls, at least until a few arrows are in it.  Can make fun games if made with different color or painted fabric with the different colors having different score values.

It's a pretty easy sewing project, by hand or machine, and great fun with several guys shooting.  

Funny thing is, I had to repost this today for a quilting group I run.  They needed some of the information in the instructions.

anyway, if it works, here is a link:
