I use big old burlap bags that used to hold coffee. Double them up, stuff them with rags, (check wifes closet)throw on a couple of zip ties and you are more than set.Easy to make, last a long time and are perfect for hanging randomly around the back forty. I spray paint an aiming point or two on the backs and even they last a long time. I will say that they weigh close to a ton when they are wet.>>>>>>>>>Whack
